The coronavirus has delayed another big event. This time it's the Democratic National Convention.

Amid ongoing questions about when traditional presidential campaigning — and the travel and large crowds it entails — will be able to resume, the Democratic National Committee has delayed its nominating convention until the week of Aug. 17. It had been scheduled for the week of July 13.

The event in Milwaukee is now scheduled for the week before the Republican National Convention, which is set to be held in Charlotte, N.C.

The daily press briefings of the White House coronavirus task force are about to become less crowded.

The White House Correspondents' Association (WHCA) had already thinned out seats in the James S. Brady Press Briefing Room in order to comply with social distancing guidelines. Now, a suspected COVID-19 case among the White House press corps means there will be even fewer reporters in the room.

WHCA president Jonathan Karl of ABC News announced Monday that an unnamed reporter who attended four briefings earlier this month has a suspected case of the virus.

Vermont Sen. Bernie Sanders is planning to stay in the 2020 Democratic presidential race despite another disappointing primary night.

Two weeks ago, Sanders was the unlikely front-runner for the nomination. Now former Vice President Joe Biden has consolidated support so rapidly, and won so many states, that Sanders is facing calls to drop out of the race.

But Sanders announced his intention to press on in a statement on Wednesday.

Democratic presidential hopefuls have stepped up their criticism of President Trump's handling of the coronavirus, accusing his administration of "incompetence."

The president has noticed. Speaking to supporters Friday night in South Carolina, he accused his Democratic rivals of using the virus for political ends.

Even now, with two early state wins and one virtual tie under its belt, and a chance to pull away from the rest of the presidential primary field on Super Tuesday, the campaign of Vermont Sen. Bernie Sanders has a bit of a chip on its shoulder about the way it says it's covered by the media.

Former Vice President Joe Biden is defending his record on Social Security, amid increased criticism from the campaign of Vermont Sen. Bernie Sanders, which has repeatedly pointed to Biden's willingness as a U.S. senator to back spending freezes for Social Security and other entitlement programs.

The candidates' back-and-forth culminated — as most disputes in modern presidential campaigns do — in dueling Twitter posts Tuesday night.

How confident are Iowa Democrats in their choices, now two weeks out from the caucuses?

The response Renee Kleinpeter gave NPR when asked which candidates she has narrowed her choice down to could sum it up: four seconds of laughter.

"I'll go with anybody who could beat [President] Trump," she said after laughing. "I wish somebody could tell me."

Leading Democratic presidential candidates on Tuesday blasted President Trump's decision to kill Iranian Maj. Gen. Qassem Soleimani, casting it as a dangerous escalation in a volatile region.

Just days after ending his campaign for president, former Housing and Urban Development Secretary Julián Castro is endorsing Massachusetts Sen. Elizabeth Warren.

The two will hold a rally together Tuesday evening in Brooklyn.

A three-month window that began with a heart attack ended as Vermont Sen. Bernie Sanders' strongest fundraising quarter yet.

Sanders' campaign announced it raised $34.5 million in October, November and December — nearly $10 million more than he had raised in the previous quarter. According to the campaign, $18 million came in from 900,000 individual donations in December alone, as Sanders drew larger and larger crowds to rallies in early voting states such as Iowa and New Hampshire.

California Sen. Kamala Harris is dropping out of the presidential race, citing a lack of funds. She informed her campaign staff of the decision on a conference call and later sent an email to supporters, in which she wrote "my campaign for president simply doesn't have the financial resources we need to continue."

Former Massachusetts Gov. Deval Patrick is making a last-minute entry into the crowded Democratic presidential primary.

A source with direct knowledge of his decision tells NPR that Patrick has been making calls to Massachusetts and national elected officials and supporters to brief them on his plans and that he plans to formally enter the race as soon as Wednesday night.

Patrick's decision is about as last minute as it gets for a candidate who still wants to compete in the key early primary states: New Hampshire's filing deadline is Friday.

Massachusetts Sen. Elizabeth Warren has been calling for President Trump's impeachment since the spring. California Sen. Kamala Harris wasn't too far behind her. New Jersey Sen. Cory Booker's been pushing for it for months.

In fact, all six U.S. senators still running for president are backing the House's impeachment inquiry.

But now that the lawmakers may be getting what they want, many political operatives see it as a train wreck for their presidential campaigns.

Former Vice President Joe Biden appears to be ramping up his attacks on President Trump. Notably, he's also ramping up his defense of his own dealings in Ukraine.
