Some of the most memorable moments of Kamala Harris' political career have come in the Senate committee hearing rooms.

The list of witnesses and nominees the California senator has flustered or put on the defensive is long, and it includes many top conservatives whom progressives villainize: Attorney General William Barr, former Attorney General Jeff Sessions, former White House chief of staff John Kelly and, perhaps atop that list, Supreme Court Justice Brett Kavanaugh.

Urging his progressive supporters to back former Vice President Joe Biden in November, Vermont Sen. Bernie Sanders framed the presidential election as an existential — maybe even apocalyptic — moment for the United States.

Former Vice President Joe Biden, the presumptive Democratic presidential nominee, has picked Sen. Kamala Harris of California as his running mate.

The selection will make Harris the third woman and first Black and first Asian American candidate to be nominated for vice president by a major political party.

Democrats met remotely Monday afternoon to approve a lengthy policy platform that seeks to balance the interests of the Democratic Party's more moderate and liberal factions.

For former Vice President Joe Biden, foreign policy isn't primarily about position papers, global summits or treaties. It's about personal connections, forged over long and repeated face-to-face meetings.

Listen to Biden talk about foreign policy on the campaign trail and you hear him come back to the same theme, over and over. "I've met every major world leader in the last 35 years — not because I'm important, but because of the nature of my job," he told a crowd in Sparks, Nev., back in January, before in-person campaigning was halted.

Presumptive Democratic presidential nominee Joe Biden wants the United States to commit $775 billion to expand access for and lower the cost of caregiving.

The proposal, which Biden outlined in a speech Tuesday afternoon, would emphasize tax credits and state funding subsidies to make child care more affordable and accessible, and make prekindergarten for 3- and 4-year-olds universal.

A joint effort by former Vice President Joe Biden and Vermont Sen. Bernie Sanders to unify Democrats around Biden's candidacy has produced a 110-page policy wish list to recommend to the party's presumptive presidential nominee.

A presidential debate scheduled for Oct. 15 will no longer be held at the University of Michigan.

University President Mark Schlissel sent a letter to the Commission on Presidential Debates explaining that coronavirus concerns made the logistics too difficult for the school to pull off.

One of a series of reports looking at Joe Biden's potential running mates

More than a month before former Vice President Joe Biden's stated deadline for naming his running mate, California Sen. Kamala Harris is seen as the consensus front-runner to become Democrats' vice presidential nominee.

Speculation about running mates can be wrong, of course. Ultimately, the choice is Biden's and Biden's alone — just as it was Barack Obama's call to tap Biden in 2008.

Former Vice President Joe Biden has mostly responded to the aftermath of George Floyd's death by contrasting his governing and leadership style with President Trump's. But the presumptive Democratic presidential nominee has also laced his speeches, interviews and campaign statements with policy specifics.

Former Vice President Joe Biden condemned both police violence and President Trump's increasingly confrontational response to widespread unrest in a Tuesday morning speech delivered at Philadelphia City Hall.

Last month, President Trump said something a lot of sports fans can relate to.

"You get tired of looking at nine-year-old baseball games, and playoff games that took place 12 years ago," he said.

With the NBA and NHL seasons suspended, and Major League Baseball hitting pause mid-spring training, fans initially flocked to the classic games that ESPN and other sports networks resorted to re-airing to fill their schedules amid the coronavirus pandemic.

In a whistleblower complaint filed this week, top federal scientist Rick Bright alleges he was removed from his post for failing to go along with the president's push to promote a drug as a cure for COVID-19.

On Wednesday, Trump dismissed the complaint, telling reporters Bright "seems like a disgruntled employee who's trying to help the Democrats win an election."

Vermont Sen. Bernie Sanders suspended his 2020 presidential campaign Wednesday, bowing to the commanding delegate lead former Vice President Joe Biden established.

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.

In the wake of three straight weeks of lopsided multistate losses to former Vice President Joe Biden, Vermont Sen. Bernie Sanders is now "having conversations with supporters to assess his campaign," according to a top aide.

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.
