The remarks were met with approval by committee members, who agreed that the department had been improperly wielded for political gain — even as Democrats and Republicans disagreed about whether such politicization occurred under the Trump or the Obama administration.

Ms. Monaco said the Justice Department’s efforts to combat domestic extremism would be among her top priorities, especially in light of the Jan. 6 attack on the Capitol by a pro-Trump mob. She said the department needed to understand how “we could have such an attack that I personally never thought I would see in my lifetime.”

She pledged to deploy law enforcement resources to learn what motivated the insurrectionists and to prevent a repeat, calling the Justice Department’s sprawling investigation into the attack “nothing less than the defense of our democracy.”

And civil libertarians have raised questions about how the F.BI. will investigate extremists for activities protected by the First Amendment.

Mr. McCarthy sought to equate the progressive policies in the bill with socialism, and said “House Democrats have abandoned any pretense of unity.”

The bill that will go before the House on Wednesday differs in notable ways from the legislation that the chamber initially approved last month. It no longer contains an increase to the federal minimum wage, which Mr. Biden had proposed and House Democrats had included in their bill, but the Senate omitted.

The bill, which cleared the Senate on Saturday, would send direct payments of up to $1,400 to many Americans and extend a $300-per-week federal unemployment benefit until early September. It would provide funding for states and local governments as well as for schools to help them reopen. The bill also contains money for coronavirus testing, contact tracing and vaccine distribution.

People close to the former president say there has been no discussion about Mr. Trump giving himself a salary. But historically, his political committees have paid to use his properties, among other things, indirectly enriching him.

Mr. Holmes also said that as the Biden administration rolled out new policies like a nearly $2 trillion relief bill, Republicans would coalesce in opposition and develop new fund-raising constituencies.

Women face their own horrors. While sexual violence by the Tatmadaw often goes unreported, rape was systematic and widespread during the ethnic cleansing of the Rohingya, Human Rights Watch found. The same fate befalls women of other ethnic groups in conflict areas.

One way to see disparities in employment that existed well before the pandemic is to look at the share who are employed among the working age population in each demographic over time. This measure, known as the employment-population ratio, has long been lower for women and Black men.

Workers on the older and younger ends of the spectrum also experienced outsize losses. Younger people, who also tend to be overrepresented in some of the most affected industries like food service, were much more likely to lose work early in the outbreak and are still among the farthest from their prepandemic employment levels. However, they have regained jobs more rapidly than older people, who may be more wary of returning to work and increasing their exposure to the coronavirus.

One common feature is that many people who lost jobs earned low wages. According to an analysis from the Economic Policy Institute, a left-leaning research group, workers in the lowest quartile of earners lost almost eight million jobs from 2019 to 2020, while the highest wage earners gained jobs.

On Thursday, President Biden will make his first prime-time television address, noting the first anniversary of the pandemic’s onset and highlighting “the role that Americans will play” in getting the country “back to normal,” Jen Psaki, the White House press secretary, told reporters on Monday.

Mr. Biden has promised that there will be enough doses for every American adult by the end of May. C.D.C. officials on Monday encouraged people to be inoculated with the first vaccine available to them, emphasizing that the vaccines are highly effective at preventing “serious Covid-19 illness, hospitalization and death.”

Even so, “it’s welcome news,” he added. “It’s the first time they are saying you can do something, as opposed to saying everything you can’t do. It’s huge.”

For example, vaccinated grandparents may visit unvaccinated healthy adult children and healthy grandchildren without masks or physical distancing.

In public areas and in places like restaurants or gyms, vaccinated people should continue to wear masks, maintain social distance and take other precautions, such as avoiding poorly ventilated spaces, covering coughs and sneezes, and often washing their hands, C.D.C. officials said.

But because those provisions last only two years, the relief bill almost guarantees that health care will be front and center in the 2022 midterm elections, when Republicans will attack the measure as a wasteful expansion of a health law they have long hated. Meantime, some liberal Democrats may complain that the changes only prove that a patchwork approach to health care coverage will never work.

The Affordable Care Act is near and dear to Mr. Biden, who memorably used an expletive to describe it as a big deal when he was vice president and President Barack Obama signed it into law in 2010. It has expanded coverage to more than 20 million Americans, cutting the uninsured rate to 10.9 percent in 2019 from 17.8 percent in 2010.

The poll found that 36 percent of Americans, and 54 percent of Democrats, favored a single national program. When asked if the government had a responsibility to provide health insurance, either through a single national program or a mix of public and private programs, 63 percent of Americans and 88 percent of Democrats said yes.

Just when Mr. Biden or Democrats would put forth such a plan remains unclear, and passage in an evenly divided Senate would be an uphill struggle. White House officials have said Mr. Biden wants to get past the coronavirus relief bill before laying out a more comprehensive domestic policy agenda.

Republicans have always said that their plan was to repeal and replace the health law, but after 10 years they have yet to come up with a replacement. Mr. Ayres said his firm is working on “coming up with some alternative health care message” that does not involve “simply throwing everybody into a government-run health care problem.”

In January, he ordered the Affordable Care Act’s health insurance marketplaces reopened to give people throttled by the pandemic economy a new chance to obtain coverage.

Yet polls show that the idea of a government-run program is gaining traction with voters. In September, the Pew Research Center reported that over the previous year, there had been an increase, especially among Democrats, in the share of Americans who say health insurance should be provided by a single national program run by the government.

The council will be co-led by Julissa Reynoso, chief of staff to Jill Biden, the first lady, and Jennifer Klein, a former senior adviser to Hillary Clinton when she was first lady. The team will have four other officials, including senior advisers who focus on policies to prevent gender-based violence and on promoting equity for Black, Latina and Indigenous women and girls.

“Let me be really clear: It’s not up to me to decide whether anyone should join a union,” he said. “But let me be even more clear: It’s not up to an employer to decide that either.”

More than 2,000 of the warehouse’s workers signed cards indicating interest in joining the union, meeting the threshold to hold a vote under National Labor Relations Board rules.

The site of the unionization drive is not insignificant. Alabama was a key battleground for the civil rights struggles of the 1960s, and many of the workers at the Bessemer facility are Black, a fact that Mr. Biden noted on Sunday. But Alabama is now a right-to-work state, making it harder for unions to organize or negotiate with employers — which has made it a draw for big companies, especially auto manufacturers.

The unionization drive takes place at a time of “reckoning on race,” Mr. Biden said, adding, “It reveals the deep disparities that still exist in our country.”

Dr. Nettles said on Tuesday that a total of 20 million doses would be ready by the end of March. The company has a contract to deliver 100 million doses by the end of June.

Johnson & Johnson looked for asymptomatic infections by checking for coronavirus antibodies 71 days after volunteers got a vaccine or a placebo. The new analyses estimate that the vaccine has an efficacy rate of 74 percent against asymptomatic infections. But that calculation was based on a relatively small number of volunteers, and the F.D.A. noted that “There is uncertainty about the interpretation of these data and definitive conclusions cannot be drawn at this time.”“I think it’s going to add to the growing evidence that the vaccines really do prevent infection as well as prevent disease,” Dr. Barouch said.

“I think the policy was shameful,” Judge Garland said. “I can’t imagine anything worse than separating parents from their children. And we will provide all of the cooperation that we possibly can.”

Progressives have pushed local governments to “defund” their police departments after killings and assaults on Black people by officers. Judge Garland said that, like President Biden, he does not “support defunding the police.”

With a sweeping set of executive orders in his initial days in office, Mr. Biden rejoined the Paris Agreement among nations to fight climate change, canceled the Keystone XL pipeline and issued a moratorium on drilling for fossil fuels on federal land, among other things.

“Our infrastructure cannot handle extreme weather events, which these fossil fuels are ironically causing.”

Social media posts mocked renewable energy as “unreliables.”

“Building resilient and sustainable infrastructure that can withstand extreme weather and a changing climate will play an integral role in creating millions of good paying, union jobs, creating a clean energy economy, and meeting the president’s goal of reaching a net zero emissions future by 2050,” said Vedant Patel, a White House assistant press secretary.

The bulk of the power loss in Texas came from natural gas suppliers, according to regulators, as pipelines froze, making it difficult for plants to get the fuel they needed. Production from coal and nuclear plants dropped as well. A similar phenomenon played out in Kansas and other states.

Ms. Boebert mentioned a photo shared repeatedly this week on social media of wind turbines she said were in Texas and apparently being de-iced by helicopter with a substance derived from fossil fuels.

In Kansas, one of few states that rely heavily on wind power, the blades on some turbines froze, too. However, just like in Texas, the bigger problem was that the state’s frigid temperatures stopped delivery of natural gas to fossil-fuel-burning power plants.

In appearance on ABC’s “This Week,” Mr. Cassidy said of the former president, “I think his force wanes,” and contended that more Republicans would come around in time to sharing his view of Mr. Trump’s guilt for the attack on the Capitol.

Many Republican voters still see Mr. Trump as the leader of the party; some senators see Mr. McConnell as the de facto leader, given his standing in the Senate and his ties to party donors.

Mr. Graham, for his part, suggested that it was Mr. McConnell, not Mr. Trump, who could face an uncertain future if Republican candidates suffer in 2022, noting Mr. McConnell’s speech criticizing the former president.

The second trial of Mr. Trump opened in the crime scene itself, the same chamber occupied on Jan. 6 by the mob that forced senators to evacuate in the middle of counting the Electoral College votes ratifying President Biden’s victory.

Mr. Schiff said his team had tried to produce an “HBO mini-series” featuring clips of witness testimony to bring to life the esoteric plot about Mr. Trump’s pressure campaign on Ukraine.

There are clips and tweets of Mr. Trump from last summer, warning he would only lose if the election was “rigged” against him; clips and tweets of him claiming victory after his loss; and clips and tweets of state officials coming to the White House as he sought to “stop the steal.”

The managers’ pretrial brief suggests they are planning to juxtapose footage of Mr. Trump urging his supporters to “fight like hell” and march to the Capitol and confront Congress with videos posted from members of the crowd who can be heard processing his words in real time.

To have any chance of making an effective case, the managers believe, they must make clear it is Mr. Trump who is on trial, not his party.

Climate scientists say vehicle electrification is one of the best ways to reduce planet-warming greenhouse gas emissions.

Gas prices are lower along the Gulf Coast and higher in California.

The new data showed hybrid cars, which run on a combination of fuel and battery power, and can sometimes be plugged in, had more mixed results for both emissions and costs.

(Battery-electric engines have fewer moving parts that can break compared with gas-powered engines and they don’t require oil changes. Electric vehicles also use regenerative braking, which reduces wear and tear.)

“With that trajectory, you can imagine that even immediately at the purchase price level, certain smaller sedans could reach purchase price parity in the next couple of years,” Dr. Gearhart said.

And a senior House Democrat asked big banks and other financial services companies on Friday to stop processing financial transactions for people and organizations that participated in the Capitol riot.

But in a fractured moment, the unified voice of the mainstream business world carries a great deal of symbolic heft.

“It’s not just a break with Trump but potentially with the Republican Party,” said Richard Edelman, chief executive of the global corporate communications firm Edelman. “It’s not OK what’s going on in America, and businesspeople are going to hold you to account.”

I mean, we had sedition and insurrection in D.C.,” said Jamie Dimon, the chief executive of JPMorgan Chase.

After the president exhorted his supporters to march on the Capitol, chief executives used their strongest language to date to repudiate Mr. Trump, and some of his longtime allies have walked away.

Ken Langone, the billionaire co-founder of Home Depot and an ardent supporter of the president, renounced Mr. Trump, telling CNBC, “I feel betrayed.”

Some companies said they were only temporarily stopping their corporate giving, but executives were sending a clear message that they were fed up with Washington.

Cisco said it would no longer donate to members who opposed the election certification, for instance, but Mr. Robbins said that did not represent a wholesale split from Republicans.

Federal agencies have also begun to identify those captured on video at the Capitol with weapons or engaging in violence and putting them on a “no-fly” list aimed at preventing suspected terrorists from boarding flights, according to an administration official.

Federal law enforcement officials have said they continue to be alarmed by an increase in chatter from groups like the boogaloo, a far-right group that aims to start a second civil war, and other racist extremists threatening to target the nation’s capital to protest Mr. Biden’s decisive victory in the popular vote and Electoral College.

Defense Department and National Guard officials said on Friday that they were pressing governors of all 50 states for reservists to fill a growing demand for security.

National Guard officials said they would most likely need at least 25,000 troops in Washington, 5,000 more than they projected this week, for duties ranging from traffic control to security in and around the Capitol itself. That number, roughly more than three times the number of American troops in Iraq, Afghanistan, Somalia and Syria, could still grow.
