Former Vice President Joe Biden took direct aim at President Trump on Tuesday, saying that Trump, who once called himself a "wartime president" taking on the coronavirus pandemic, seems to have now "surrendered."

"Remember when he exhorted the nation to sacrifice together in the face of this ... 'invisible enemy'? What happened? Now it's almost July, and it seems like our wartime president has surrendered," Biden said in prepared remarks.

The Democratic Party's more establishment wing is victorious in a high-profile Kentucky Senate primary despite a late surge from a rising progressive lawmaker.

Retired Marine fighter pilot Amy McGrath has beaten state Rep. Charles Booker in the state's Democratic U.S. Senate contest, The Associated Press projects.

The call came Tuesday, a week after the primary, as absentee ballots were counted.

McGrath will now face Senate Majority Leader Mitch McConnell, who easily won the Republican primary.

A progressive shift underway in Colorado Democratic politics is spotlighted Tuesday in the primary for a U.S. Senate race that will likely help decide control of the chamber.

The contest between former Gov. John Hickenlooper and former state House Speaker Andrew Romanoff is the marquee race on Tuesday, but other themes are at play elsewhere, as voters also head to the polls in Utah and Oklahoma:

• Former Gov. Jon Huntsman is looking to make a comeback in Utah.

Progressives are mounting efforts to best establishment Democrats in Kentucky and New York Tuesday.

Black Lives Matter protests around the country have added energy to the left, and Black progressives are surging in contests in both states.

In Kentucky, the race between the two leading Democrats vying for the right to likely take on Republican Senate Majority Leader Mitch McConnell is coming down to the wire. All the momentum is on the side of state Rep. Charles Booker over Amy McGrath, a retired Marine fighter pilot with a lot of money and the party's backing.

Former Georgia gubernatorial candidate Stacey Abrams says the state's Tuesday primary performance was "an unmitigated disaster," pinning the blame on Georgia's Secretary of State Brad Raffensperger.

Former Vice President Joe Biden again denied the sexual assault allegation made against him by former Senate staffer Tara Reade in an interview on MSNBC Thursday night, but added that voters who stand by Reade should not support him.

"If they believe Tara Reade, they probably shouldn't vote for me," Biden said when asked what message he would give to female voters who accept Reade's allegation as true, but were planning on supporting him.

"I wouldn't vote for me if I believed Tara Reade," Biden added.

Former Vice President Joe Biden formally began the process of selecting a running mate on Thursday morning, releasing the names of former and current Democratic officials who will lead his search for a vice presidential candidate, who Biden has said will be a woman.

Former Connecticut Sen. Chris Dodd, Delaware Rep. Lisa Blunt Rochester, Los Angeles Mayor Eric Garcetti and Cynthia C. Hogan, a top aide to Biden in the Senate and White House, will lead the search over the coming months.

Testing is the key that will unlock normalization for millions of Americans.

It's the doorway between the disaster response mode of the pandemic and confidence about returning to work, school and life. And it's also still apparently weeks or more away from scaling to a level that will make a big difference for most people in most places.

Precisely how far away isn't clear, although President Trump and a pageant of guests attempted on Monday to sell the idea that victory is just around the corner.

A few weeks ago, Georgia Democratic Senate candidate Jon Ossoff held his first digital organizing event over the video conferencing service Zoom, geared at teaching volunteers how to conduct phone banks from home.

"There is nothing more effective than going door to door and having those face-to-face conversations," Ossoff told over 70 attendees. Since moving his primary campaign online over a month ago, the campaign held several virtual town halls and events with local political organizations.

A month ago, President Trump went on Fox and downplayed the potential lethality of the novel coronavirus and compared it to the seasonal flu.

After intense political back and forth, Wisconsin is holding its presidential primaries and elections for many state and local offices on Tuesday.

Former Vice President Joe Biden says he finds it "hard to envision" an in-person Democratic National Convention taking place in July as planned.

"The fact is, it may have to be different," the leading Democratic presidential candidate said in an interview with MSNBC on Tuesday night.

The Democratic National Convention is scheduled to take place from July 13-16 in Milwaukee. The Republican National Convention is planned for Aug. 24-27 in Charlotte, N.C., and neither party has announced alternative plans.

Jaylan Scott was in the middle of planning an upcoming event for the Young Democrats of Georgia when he found out his state's primary was postponed.

"It was pretty much a shocker for me," the Georgia State University sophomore said. "It was a shocker for everybody."

Scott first voted in the 2018 midterm elections but has yet to participate in a presidential election. He's a supporter of Vermont Sen. Bernie Sanders, but says he'll vote for former Vice President Joe Biden if he is the Democratic nominee.

Amid the coronavirus pandemic, the 11th Democratic presidential debate, on Sunday, is set to look and sound quite different from the previous 10.

Writer, entrepreneur and spiritual leader Marianne Williamson has ended her presidential campaign, months after garnering viral attention in early debates, earning curiosity but little support from Democratic voters.

"The primaries might be tightly contested among the top contenders, and I don't want to get in the way of a progressive candidate winning any of them," Williamson wrote in a letter to supporters. "As of today, therefore, I'm suspending my campaign."

President Trump ordered an airstrike on Thursday evening that killed the Iranian General Qassem Soleimani in Baghdad, a man he said was "plotting imminent and sinister attacks" against Americans in the region.

Soleimani was the leader of the Quds Force, a covert section of the Islamic Revolutionary Guard Corps. The White House says he was the mastermind behind attacks on Americans during the past two decades — including two recent attacks.

Castro served as secretary of housing and urban development in the Obama administration and, before that, was mayor of San Antonio, Texas.

House Intelligence Committee Chairman Adam Schiff, D-Calif., has released a report that outlines the findings from public hearings and closed-door interviews conducted by impeachment investigators since late September.

As part of the impeachment inquiry, the House Intelligence Committee has released the transcript of the testimony by Philip Reeker, the acting assistant secretary of state who is responsible for European affairs.

Reeker testified for eight hours on Oct. 26, complying with a subpoena despite pressure from the White House to defy the request.

According to a source familiar with his testimony, Reeker was prevented by high-ranking State Department officials from aiding Marie Yovanovitch, then U.S. ambassador to Ukraine, before she was recalled from her position.

House impeachment investigators have released the transcript of the deposition of Mark Sandy, a career staffer for the White House Office of Management and Budget.

Sandy was deposed by lawmakers on Nov. 16 and was the lone person from the OMB to testify. Top-ranking political appointees to the OMB — including Russell Vought, its acting director — refused to comply with the investigation's requests, citing advice from the White House counsel's office.

Two more witnesses testify Thursday morning in front of the House Intelligence Committee, marking the end of this week's public impeachment hearings.

Fiona Hill, the former Russia director for the National Security Council, and David Holmes, a U.S. diplomat from the U.S. Embassy in Kyiv, are appearing before investigators.

Over the past three days, lawmakers have spent hours questioning a total of nine U.S. officials (including Hill and Holmes).

No additional hearings have been announced by the Intelligence Committee.
