President Donald Trump made 115 false claims over the last two weeks of February, during which he faced a growing crisis over the coronavirus pandemic, visited India, held four campaign rallies and addressed the Conservative Political Action Conference.Trump made 67 false claims from February 17 through February 23; that was the 11th-highest total of the 34 weeks we've fact checked at CNN. He added 48 false claims from February 24 through March 1; that week ranked 25th out of 34. As usual, many of the false claims were ones he has uttered before.

aim: "Russia, if you're listenin

The fact that there is notorious video footage showing all this has not stopped Trump from making up an alternative history. He told CPAC on February 29 that he said "Russia, if you're listening" as "a joke," in front "25,000 people," and he was "laughing" afterward along with others in the crowd -- but the media cut off the clip "so quick at the end" so that people couldn't hear all of this laughing.

"Let's talk about the Joe we know," Harris said Monday as she gave her endorsement of the former vice president. "I am so proud to endorse Joe Biden to be the next president of the United States. I believe in Joe."

The Biden-Harris relationship was tested during a fiery primary campaign, especially when the California senator pointedly went after the former vice president for his decades-old fight against busing to desegregate schools and his comments about his ability to work with segregationist senators.

The former vice president has been open about the pain that his son's death in 2015 to brain cancer has caused him, referring to his late son as "his soul" and often relating the tragedy he felt with pain that voters feel, too.

While holding a press conference on Friday in Atlanta about the current coronavirus outbreak, President Donald Trump said that he didn't know people died of the flu. His grandfather died of influenza in 1918, according to Trump biographer Gwenda Blair.

Trump is right that tens of thousands of Americans die each season from the flu. The CDC estimates that there were more than 34,000 deaths from the flu in the 2018-2019 flu season. The previous season that number was estimated to be more than 61,000.

Blair: He is not a student of history. He's only looking forward. He has no rearview mirror and that means he learns little. There's that old cliche about people who don't learn from history are bound to repeat it, and I think that's what he's currently in the middle of re-enacting.

"And if Joe is the candidate, I'll do everything I can to make sure that he does (win)," Sanders said.

"Well, I'm not going to speculate. We would love to have Sen. Warren's support and we would love to have the millions of people who supported Sen. Warren in her campaign on board," Sanders said.

"We're working as hard as we can because Michigan is very, very significant in terms of the primary process. We hope to repeat the victory we had in 2016," he said, adding later that he thinks his proposed agenda will help him claim another victory in the state.

During an interview with CNN's Jake Tapper on "State of the Union," Sanders was asked if he thinks "sexism and other forms of bigotry remain hurdles for candidates appealing for not just the general electorate but for the Democratic votes."

Their departures left just one woman -- Rep. Tulsi Gabbard of Hawaii -- in a race that once saw six women vying for the nomination and raised questions about the challenges women face when they campaign for an office that has yet to be held by someone other than a man.

"On the other hand, we have made progress in the last 40, 50 years in terms of the number of women who are now in the Congress. You can remember it wasn't so many years ago -- few decades ago -- that Barbara Mikulski of Maryland was the only woman in the United States Senate, and we have made some progress," the Vermont senator said. "But the day has got to come sooner and later that women can see themselves equally represented in Congress -- half or more members of Congress, president of the United States, leaders of companies all over this country."Read More"We have got to get rid of all of the vestiges of sexism that exist in this country, which is still pretty rampant," Sanders added.

Almost 90% of the world's men, and women, are biased in some way against women, according to the Gender Social Norms Index. Half of men and women feel that men make better political leaders. More than 56% feel that men have more right to a job and/or make better business executives.

Around the world, women are equally likely to vote, but only 10% out of 193 heads of government are female, according to the Pew Research Center. Women are overrepresented in low-wage employment, but represent only 21% of employers and 12% of billionaires. They are about equally represented in jobs at S&P Fortune 500 companies, but represent only 5.8% of the total CEOs, the index found.

People's reactions to a woman's pregnancy at work is a good example of how much bias still exists. In the United States, as recently as 2011, some employers still fired employees on the spot who had become pregnant, according to a report by the Center for WorkLife Law at the University of California's Hastings College of the Law. (That's illegal.) More subtly, women announcing a pregnancy may be taken off the partner track or denied raises and bonuses. (Also illegal.) A pregnancy can easily reset the course of a woman's career. Pregnancy discrimination is widespread and difficult to police.

No matter how much President Donald Trump and his acolytes persist in trying to minimize the dangers of the coronavirus, the rest of the world -- and the virus -- are not following his lead.

As the number of cases kept climbing, the virus continued to drive uncertainty in the stock market, which fell steeply following the start of an oil price war. Trump flailed desperately on Twitter, and his Health and Human Services Secretary, of all people, raved in support of his boss that the economic fundamentals are "unbelievable."

Unlike during the 2008 Great Recession, when the government leaped to assist financial institutions, the first priority this time should be helping individuals in need. Only then should we help businesses caught in this storm.

A big story of the Democratic primaries is the rise of the so-called pragmatic black voters who revived former Vice President Joe Biden's flagging presidential campaign. But there's a flip side to this story that no one is paying attention to: What happened to all those radical black voters who should be rallying to Sen. Bernie Sanders' side?

The Rev. Martin Luther King Jr. was a socialist, according to many historians.  W.E.B. DuBois was a socialist,  and so were civil rights leaders A. Philip Randolph and  Bayard Rustin. The most prominent black philosopher today,  Cornel West,  is a socialist and Sanders' supporter. Hip-hop artists, such as rapper "Killer Mike" and Chuck D of Public Enemy, are also big Sanders supporters.

Slavery, for example, was driven as much by greed as racism. And blacks lost half  of their wealth due to the 2008

"You can't have capitalism without racism," Malcolm X once  said.

The Midwestern states that begin voting Tuesday with primaries in Missouri and Michigan represent the Vermont independent's best -- and possibly last -- chance to regain his footing in the Democratic presidential race after former Vice President Joe Biden reestablished himself as the front-runner with commanding Super Tuesday victories last week.

If Sanders can't win in the states that vote over the next month across the industrial heartland -- a list that extends from Michigan and Missouri on Tuesday to Ohio and Illinois on March 17 and Wisconsin on April 7 -- the senator may find it difficult to justify continuing what he calls "a campaign of the working class, by the working class and for the working class," as he put it in a Detroit rally Friday night.

Primaries are being held in Idaho, Michigan, Mississippi, Missouri and Washington, and the North Dakota Democratic caucuses are also taking place the same day.

The White House insists President Donald Trump doesn't need a coronavirus test, despite several members of his political circle self-quarantining after they came into contact with a man later diagnosed with the disease.

They include Florida GOP Rep. Matt Gaetz, who rode in "The Beast" limousine with Trump in the Sunshine State on Monday, before climbing up the steps of Air Force One behind the President. Incoming White House chief of staff Mark Meadows is also staying home until Wednesday despite his test coming back negative. Another Trump friend, Rep. Doug Collins, a Georgia Republican, was pictured shaking hands with the President on Friday.

The issue of Trump's health coincided with an alarming day as the number of infected Americans rose above 700, hard-hit Italy went into total lockdown and Wall Street stocks crashed to their worst day since the Great Recession amid widening fears that the crisis could tip the economy into a recession. The Securities and Exchange Commission on Monday asked all personnel based at its headquarters to work from home due to an employee who may have the virus, becoming the first federal agency to ask its Washington employees to stay home.

Eight days ago, the political world was preparing for one of two scenarios:1) Bernie Sanders runs away with key Super Tuesday states like California and Texas -- and, in so doing, builds a delegate lead that begins to look insurmountable2) Joe Biden shows some strength on Super Tuesday, staying within shouting distance of Sanders in the delegate count and setting up an extended delegate battle between the two men.

Instead, a third scenario developed: Biden racked up a series of unexpected wins in places likes Texas, Minnesota and Massachusetts and kept it relatively close in California -- producing a delegate lead for the former vice president heading into Super Tuesday II tomorrow.

As the Democratic race has become a two-man contest between Biden and Sanders, multiple sources say. Trump has been frustrated by the former vice president's comeback. That was evident in the call the campaign held Sunday night — something they now say they will do so periodically until November — as officials contended that electing Biden is the same as electing Sanders.

While Sanders has energized the progressive wing, Biden has focused on rallying centrists around him, and both have argued they are better suited to defeat Trump.

A primary concern for the Trump campaign if Biden is the nominee will be how he performs in states that are critical to the President's re-election like Pennsylvania, Michigan and Wisconsin. But publicly, the campaign insisted Biden wouldn't be competitive with Trump in those states and discounted his blue-collar appeal during the call, arguing his past positions on trade have damaged him.

Since his resounding victory in the South Carolina primary, Biden has snagged over 40 endorsements from members of Congress and governors. On Monday, Sen. Cory Booker offered his support, a day after Biden's campaign announced that he secured the backing of another former rival of his in the Democratic presidential race, California Sen. Kamala Harris.

There have been 14 party primaries without an incumbent running since 1980. The leader in endorsements from members of Congress and governors this long after the Iowa caucuses have won 11 out of 14 of them (79%). This success rate undersells Biden because the people winning in endorsements who went on to lose were trailing in the national polls.

Former Vice President Joe Biden has a double-digit lead over Vermont Sen. Bernie Sanders for the Democratic presidential nomination, a new CNN poll of Democratic voters nationwide conducted by SSRS shows.

The poll finds 52% of registered voters who are Democrats or Democratic-leaning independents say they want to see Biden win the nomination, while 36% say they'd rather see Sanders win.

Just as suddenly as the Democratic race narrowed to a one-on-one showdown between the Vermont senator and former Vice President Joe Biden, it's brought a primary that Sanders needs to win -- or his path to the Democratic nomination could quickly evaporate.

Four years ago, Sanders' stunning victory in Michigan slowed Hillary Clinton's march to the party's nomination and foreshadowed a struggle with working-class voters across the upper Midwest that would ultimately lead to President Donald Trump's election.

Fissures between the White House and national health agencies, including the Centers for Disease Control and Prevention, have begun to expand as the coronavirus pandemic spreads to more American states, creating dissonance between President Donald Trump and the professionals tasked with containing the virus further.

The cracks are falling along predictable lines. While health officials have sought to present a realistic and cautious picture of the national situation, Trump and his political allies are hoping to relay an altogether different message: that the virus is contained, Americans face little risk, and life should proceed as normal.

From its earliest days, Trump has sought to downplay coronavirus' risks and lashed out when those within his administration appeared to be doing otherwise. He told a collective of executives at the World Economic Summit in Davos, Switzerland, in mid-January that it would not pose a major threat to the United States, an attendee told CNN.

Almost a third of the Earth will need to be protected by 2030 and pollution cut by half to save our remaining wildlife, as we enter the planet's sixth era of mass extinction, according to a United Nations agency.

"Biodiversity, and the benefits it provides, is fundamental to human well-being and a healthy planet," the draft plan reads. "Despite ongoing efforts, biodiversity is deteriorating worldwide and this decline is projected to continue or worsen under business-as-usual scenarios."

The convention aims to stabilize our fragile biodiversity by 2030 and allow ecosystems to recover by 2050, allowing for a final vision of "living in harmony with nature" -- but these goals will require urgent action on both local and global levels.

The world's oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second, scientists have said.

"The upward trend is relentless, and so we can say with confidence that most of the warming is man-made climate change," said Kevin Trenberth, distinguished senior scientist in the Climate Analysis Section at the National Center for Atmospheric Research.

"There are no reasonable alternatives aside from the human emissions of heat trapping gases to explain this heating," Cheng said, adding that to reach this temperature, the ocean would have taken in 228,000,000,000,000,000,000,000 -- or 228 sextillion -- joules of heat.

Scientists know that the ingredients necessary to form life appeared on Earth early in its history, but they're still trying to figure out exactly how that happened. A new study suggests that comets were the cosmic messengers depositing crucial elements like phosphorus on Earth billions of years ago.

The molecules containing phosphorus are made in the wake of massive stars as they form. Young stars release gas flows that carve pathways through clouds in interstellar space. Phosphorus builds up on the walls of these pathways as the stars release radiation, and phosphorus monoxide is created in abundance.

Rosetta and its ROSINA instrument, the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis, detected phosphorus in a haze around the comet. But at the time, the scientists weren't sure how phosphorus got there in the first place.
