Tom Steyer on Tuesday swiftly shut down rumors that he is dropping out of the Democratic presidential race.

After the polls closed in New Hampshire, a reporter tweeted that Steyer, a billionaire hedge fund manager and philanthropist, told supporters he was ending his presidential campaign. Steyer quickly released a statement, saying the results show "the race for the Democratic nomination is wide open. Until Nevada and South Carolina have the chance to vote, we won't know which candidates can build the diverse and unified coalition we need to win in November."

In order to defeat President Trump, "we need to expose him as a fraud and failure on the economy, and we need to build a diverse, national coalition," Steyer continued. "I believe the candidates who do well in Nevada and South Carolina will head into Super Tuesday with the proven ability to build such a diverse coalition." With 82.6 percent of New Hampshire precincts reporting, Steyer has 3.5 percent of the vote. Catherine Garcia

Former Democratic presidential candidate Marianne Williamson announced on Sunday that she is endorsing Sen. Bernie Sanders (I-Vt.).

During a surprise appearance at Sanders' rally in Austin, Texas, Williamson said he "has been taking a stand for a very long time. He has been consistent, he has been convicted, he has been committed. And now it's time, I'm here and you're here, because it's time for us to take a stand with Bernie."

She also rejected the idea that Sanders can't defeat President Trump in November. "I'll tell you what's already happened to those who say it cannot happen," Williamson said. "You just tell them this: It already happened. He won Iowa. It already happened, he won New Hampshire. It already happened, he won Nevada." His supporters are "tired of saying pretty please," she added. "We're going to stand up, we're going to show up because we woke up. We're here and we're with Bernie." Williamson, who also endorsed Sanders when he ran for president in 2016, exited the race in early January. Catherine Garcia

The Trump administration appears divided over whether to alter some expiring aspects of the Foreign Intelligence Surveillance Act, The Wall Street Journal reports.

Some White House officials within the Domestic Policy Council, spurred by the surveillance of former Trump campaign adviser Carter Page which has since been called into question, are hoping to overhaul parts of FISA which are soon due to lapse. One change they're proposing, which has actually been pushed for a long time by groups like the American Civil Liberties Union, is to eventually notify subjects of national-security surveillance that they had been surveilled.

There will likely be some hurdles, though. The National Security Council, for example, generally advocates for expanded surveillance powers, and some other administration officials reportedly have privately expressed concern that the effort to scale back some of the spying powers may go too far.

President Trump hasn't said anything about the expiring segments of FISA, but he has complained about the law in relation to Page and his campaign. Still, per the Journal, presidents historically have avoided scaling back surveillance powers because they fear they'll be blamed in the event of a terrorist attack.

If you saw the reports that Sen. Bernie Sanders (I-Vt.) was briefed by U.S. intelligence agencies that Russia was trying to aid his Democratic presidential campaign, you might have wondered, why exactly, Moscow was targeting him. After all, President Trump is still apparently the candidate the Kremlin hopes wins, and Sanders and Trump certainly have different ideological stances.

GQ's Julia Ioffe set out to answer that question, and while she reports that some people think Sanders' non-interventionist foreign policy platform is appealing to Moscow, or that he will be easier for Trump to defeat than other more moderate candidates, she also found that it may be more about optics. "The ideal scenario is to maintain schism and uncertainty in the States till the end," said Gleb Pavlovsky, a Russian political scientist who used to advise Russian President Vladimir Putin. "Our candidate is chaos."

Essentially, as described by Ioffe's sources, Moscow is licking its chops over what could be the most extreme U.S. presidential election in quite some time, if not ever, and they want to see the country turn on itself. "All of this infighting, this cannibalism, they create and deepen the crisis of the American system," said Andranik Migranyan, a close friend of Russian Foreign Minister Sergei Lavrov who used to run a Russian government-funded think tank.

Migranyan went on to question — perhaps facetiously — whether the U.S. will still exist after 2025. "Your country is hurtling toward the abyss," he said.

Of course, it's unclear if that's precisely why the Kremlin seems okay with a Sanders victory — and Migranyan denies Russia is actually meddling — but it's not difficult to imagine Moscow would enjoy an even more hotly contested election than in 2016. Read more at GQ. Tim O'Donnell

Sen. Bernie Sanders (I-Vt.) may be basking in his victory after the Nevada caucuses, but he can't celebrate for too long. The South Carolina primary is right around the corner, and despite Sanders steadily encroaching into first place for weeks in state polls, it's still former Vice President Joe Biden's state to lose in the week leading up to the vote, a new CBS/YouGov poll revealed Sunday.

Sanders crushed his competition in Nevada, where Biden finished a distant second. South Carolina, though, has always been the early voting state the vice president has had his eye on — and he's still got a chance — but Sanders is right behind him now as Biden's once dominant lead has shrunk to just a five-point advantage over Sanders in the new poll.

Some of that likely has to do with Biden's support among black voters shrinking over the last few months. He still maintains the edge, but billionaire Tom Steyer has shot up to second place among the demographic thanks to a furious final effort in the state. Steyer, in fact, is in third place in the poll, which must excite his campaign, considering he told Fox News' Chris Wallace on Sunday that he'll need a top-three finish next Saturday to get back into the race.

The CBS News survey was conducted by YouGov between February 20-22, 2020. A representative sample of 2,000 registered voters in South Carolina was selected, including 1,238 self-identified Democrats, as well as independents who plan to vote in the Democratic primary this year. The margin of error is 5.5 points. Tim O'Donnell

President Trump continues to ride the Sen. Bernie Sanders (I-Vt.) bandwagon, but some analysts think he and his Republican supporters might want to think twice about what they're wishing for.

Trump on Sunday congratulated Sanders on his big win at the Nevada caucuses, which helped increase his lead in the Democratic presidential primary substantially, making him the frontrunner to take on Trump in the general election in November. The president said it remains to be seen if Sanders can hold on, but he just hopes the Democratic Party treats Sanders fairly, perhaps hinting that he believes there may be some sort of effort from more establishment Democrats to stop Sanders' victory from happening.

Not everyone is buying Trump's call for fairness, though. Former Obama adviser David Axelrod, for example, thinks Trump is doing what he can to divide Democrats to boost his own re-election bid.

There's also the notion out there that Trump and his supporters believe Sanders gives them the best shot at staying in the White House because the senator's more extreme ideological leanings will turn swing voters back to the GOP. But CNN political commentator Mark McKinnon, who worked for former President George W. Bush, believes Republicans may be too sure of themselves, especially because Sanders is able to rile up passion in his supporters in a fashion similar to Trump himself. Tim O'Donnell

Rep. Jim Clyburn (D-S.C.) thinks that even if Sen. Bernie Sanders (I-Vt.) proves himself to be the preferred candidate of the Democratic Party nationwide, his win could have consequences down the line.

During an appearance on ABC's This Week, host George Stephanopoulos asked Clyburn if a victory from Sanders, who describes himself as a Democratic Socialist, could harm the Democrats' chances of maintaining its majority in the House. Clyburn said it will likely add an "extra burden" in some places — like the more moderate and conservatives districts in South Carolina — where Democrats pulled upsets in the last midterm election. Clyburn said it'll be a challenge to hold on to those districts if candidates have to advocate for a democratic socialist.

"South Carolinians are pretty leery about that title 'socialist,'" he said.

Clyburn also said he'll finally make an endorsement this coming Wednesday, the morning after Tuesday's debate in South Carolina. Clyburn serves as the majority whip, and his support will likely go a long way in the Palmetto State, though it seems unlikely Sanders will get the nod. Tim O'Donnell
