Mr. Biden will be the first true creature of Capitol Hill to occupy the White House since President Gerald R. Ford in the 1970s. More than recent predecessors, he understands how other politicians think and what drives them. But his confidence that he can make deals with Republicans is born of an era when bipartisan cooperation was valued rather than scorned and he may find that today’s Washington has become so tribal that the old ways no longer apply.

“American citizens feel like they’ve been attacked. Fear’s reaction is anger, anger’s reaction is patriotism and voilà — you get a war,” said Mr. Lee’s co-host, who gave his name as Rampage.

However, the US National Archives has already announced - through a tweet - that it will archive all social media content from that account, despite Twitter's lack of a commitment to doing so.

For electric cars, lower maintenance costs and the lower costs of charging compared with gasoline prices tend to offset the higher upfront price over time. (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.)

The cars are greener over time, too, despite the more emissions-intensive battery manufacturing process. Dr. Trancik estimates that an electric vehicle’s production emissions would be offset in anywhere from six to 18 months, depending on how clean the energy grid is where the car is charging.

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. Some hybrids were cheaper and spewed less planet-warming carbon dioxide than regular cars, but others were in the same emissions and cost range as gas-only vehicles.

The F.B.I. is investigating 37 people related to the killing of Officer Brian Sicknick, the Capitol Police officer who died after being injured during the pro-Trump riot on Jan. 6, according to an F.B.I. memo sent to the private sector and others on Friday. The Times obtained a copy of the report.

“The increasing problem now is there is not enough supply of vaccine to keep up with the first appointments, let alone the second appointments,” Mr. de Blasio said on Friday.

At 5:30 p.m. Tuesday, the evening before Mr. Biden takes the oath, the committee will hold a lighting ceremony around the Lincoln Memorial Reflecting Pool in remembrance of people in the United States who have lost their lives in the coronavirus pandemic.

For weeks, Washington has been preparing for the possibility of protesters. But the nation’s capital was kicked into high alert after a violent mob breached the Capitol building and forced lawmakers to halt the official counting of Electoral College votes to affirm Mr. Biden’s victory.

President Trump announced Friday that he would not attend Mr. Biden’s inauguration.Mr. Biden called that decision “one of the few things he and I have ever agreed on.”Still, it is a major break with tradition for a president to skip the ceremonial heart of the country’s democracy: the peaceful transfer of power.

Vice President Mike Pence will attend, an aide said Saturday, after Mr. Biden made clear on Friday that he was welcome.AdvertisementContinue reading the main story

China froze a $15 trillion economy last February. It used brute force to isolate cities and provinces and drag people into quarantine.AdvertisementContinue reading the main story

Beijing has a harder time fixing other problems. Shoppers remain skittish, and may become more so as the virus has resurfaced in several cities lately. Its economy still relies less on innovation and services than on making stuff. Legions of college graduates still find satisfying jobs in short supply.

The villagers in Changmingzhen may not agree. It is in southwestern China’s Guizhou Province, in a county that was so poor five years ago that it became a target for China’s antipoverty campaign.

One in 860 Americans have died of Covid-19 in the last year, according to new figures released by the C.D.C. But the burden of deaths has not fallen equally across racial, ethnic lines and geographic regions, and there is concern that vaccines will not reach the hardest hit communities, where access to health services is limited and distrust is rampant.

But spikes in cases threaten to cripple already overwhelmed hospitals and nursing homes in many parts of the country. Some are at or near capacity. Others have faced troubling rates of infection among their staff, causing shortages and increasing patient loads.

If the variant is about 50 percent more contagious, as suggested by data from Britain, it will become the predominant source of all infections in the United States by March, the model showed. A slow rollout of vaccinations will hasten that fate.

In another, an officer assigned to protect high-ranking lawmakers racked up two charges of drunken driving, including one case in which his car struck a Maryland State Police trooper’s unmarked cruiser. The officer continued to climb the ranks, despite an internal investigation for overtime fraud.

The responsibilities of the Capitol Police are vastly different from those of ordinary police departments. The force protects the Capitol grounds, members of Congress and staff, and it screens millions of visitors a year. Officers are expected to recognize the 535 lawmakers and to avoid offending them.

The delicacy of that task was on full display in 1983, when a House inquiry found that the Capitol Police had botched a drug investigation by creating “the impression that the investigation may have been terminated to protect members” — while noting that, to be sure, no members had been implicated.

Allegations of gender discrimination have dogged the department for years. In lawsuits, female officers have described a culture of sexual harassment, with commanders rarely punished for lewd remarks or for sleeping with subordinates

And whereas the conservative argument against a post-Jan. 20 impeachment presupposes that the matter will inevitably end up in the courts (which may be sympathetic to Mr. Trump), that claim, too, is erroneous.

The House on Wednesday voted for a historic second impeachment of President Trump, approving 232 to 197 a single article citing his role in whipping up a mob that stormed the Capitol last week. But as his fellow Democrats denounced the assault and Mr. Trump’s incitement of the rioters, President-elect Joseph R. Biden Jr. has maintained a studied cool, staying largely removed from the proceedings and keeping his focus on battling the coronavirus pandemic, reviving a faltering economy and lowering the political temperature.

A man who was photographed holding a Confederate battle flag inside the U.S. Capitol last week during the riot was arrested Thursday in Delaware, two law enforcement officials said. The man, Kevin Seefried, was wanted by the F.B.I., which had sought help from the public to identify him and had widely circulated a dispatch plastered with images of him.

A retired firefighter from Chester, Pa., was also arrested on Thursday after he was identified as the man seen in a video throwing a fire extinguisher at police officers during the riot. The man, Robert Sanford, is charged with assaulting a law enforcement officer engaged in the performance of official duties and civil disorder among other crimes.

The landscape of addiction in America looks different today than it did decades ago. Now, we have a real chance to flip the script on opioid abuse. “I learned because of Fred. I learned,” President Trump says. “It is time to liberate our communities from this scourge of drug addiction.”

Mr. Biden has said he will work to build Republican support for his plans, and he will need 10 Republican votes in the Senate to overcome a filibuster. But top Democrats in the House and Senate are preparing to pivot quickly to a parliamentary process known as budget reconciliation in the event they can get only a simple majority in the Senate. Republicans used the procedure to bypass a filibuster and approve Mr. Trump’s signature tax cuts in 2017.

If a Senate trial resulted in Mr. Trump’s conviction, it held out the prospect, tantalizing for Democrats and many Republicans alike, of barring him from ever holding office again.

At least five people did die during the attack, including an officer and a member of the mob who was shot just outside the chamber door

Signs of a Biden win: If the polls are right and the count is on track, Mr. Biden is probably getting a Wisconsin and Nevada call on election night. Georgia’s another possibility — if Mr. Biden is going to win the state, he has probably caught up to Mr. Trump by now. If the night’s going really well for Mr. Biden, maybe he’s still competitive or even leading in Iowa, Ohio or Texas.AdvertisementContinue reading the main storyMichigan and Pennsylvania? Well, we’re just going to have to wait and see. Of the two, Michigan seems more plausible.Exactly where will the count stand in Michigan and Pennsylvania if Mr. Biden’s on track for victory? It depends on how many absentee ballots they get through, of course. If they haven’t counted many mail ballots, Mr. Trump could even lead by double digits.The better measure: Focus on any counties that manage to wrap up their count. I’d guess some will get pretty close. If Mr. Biden’s winning, he will start to outrun Mrs. Clinton’s 2016 showing in the counties that get through their mail votes. That could be the tell.Signs of a Trump win: If the president’s on track, the race in Nevada and Wisconsin might be too close to call. Even if he eventually loses Wisconsin, he might hold on to the lead all the way until we get the absentees from Milwaukee. He probably already got the call in that long list of states where Mr. Biden’s hoping to squeak out a win, like Ohio and so on.The most important sign would be a lead in Pennsylvania and Michigan. In Pennsylvania, it could easily be a double-digit lead, depending on just how many absentee ballots have been counted. With Mr. Biden holding such a commanding lead among the third of the electorate that voted early, a Trump win most likely involves a double-digit victory on Election Day — and a double-digit lead in the count, late into the night.

This year’s mail-in vote totals will climb well past the nearly 64 million that election officials had recorded through Monday. Some ballots have already arrived at election offices around the country but have not yet been entered into the system. Others have been mailed, but not yet delivered.

Dr. McDonald, who tracks election statistics, says that, as of Tuesday, just over 28 million absentee ballots requested by voters had not been entered as returned to election officials. In an analysis posted on his website, he said that those ballots are rightly a concern to Democrats, but that there still may be time for many of them to be counted.

The most intense attention was on the swing state of Florida and its 29 Electoral College votes. There, Mr. Trump was overperforming his 2016 vote totals in the populous Miami-Dade County, with 526,000-plus votes so far counted in 2020 compared with about 334,000 total four years ago — an enormous improvement.

Florida is a critical part of almost any Electoral College pathway for Mr. Trump to hit the 270 votes needed to secure re-election. Mr. Biden is seen to have multiple paths without the state.

In populous Miami-Dade, Mr. Trump was overperforming his 2016 vote totals, with 512,000-plus votes so far counted in 2020 compared with about 334,000 total four years ago — an enormous improvement.
