President Trump has mused about delaying this year's election based on unsupported conspiracy theorizing about the integrity of voting during the coronavirus disaster.

In a Twitter post on Thursday, Trump repeated what has become a pet theme about the prospect of inaccuracies or fraud with mail-in voting.

A day after defending his right to hold campaign events in the midst of spikes in coronavirus cases, Vice President Pence and the Trump campaign are postponing two events he was to headline next week in Florida and Arizona.

The states are two of the hardest hit in recent days, and health officials have encouraged people to avoid large in-person gatherings. The events have been postponed "out of an abundance of caution," two campaign officials told NPR.

It's a remarkable reversal for Pence, who on Friday forcefully defended his plan to move forward with the campaign events.

President Trump addressed the graduating class of the U.S. Military Academy on Saturday as the nation continues to grapple with a public health crisis and unrest following the police killing of George Floyd.

The president delivered his remarks at West Point to an audience of more than 1,000 graduating cadets. The in-person speech was a break from the video addresses that have been ubiquitous this graduation season.

President Trump defended what he called a "very symbolic" photo-op on Monday in front of St. John's Church and dismissed a suggestion that he needed to do more to comfort the nation after the death of George Floyd, saying that cracking down on violent protests was paramount.

Escalating his rhetoric during a period of roiling national crises, President Trump on Monday threatened to deploy the U.S. military to cities or states that don't take "necessary" actions to halt violent protests, saying the armed forces will "quickly solve the problem for them."

Trump's Rose Garden remarks came as just across the street, law enforcement officers deployed tear gas and shot rubber bullets to forcefully disperse peaceful protesters. Washington, D.C., had set a curfew Monday of 7 p.m. ET.

This story was updated on June 1 to include WHO's reaction from its daily press conference.

Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, said he learned of President Trump's intentions of "terminating" the decades-long U.S. relationship with WHO through Trump's press briefing on Friday.

Joe Biden, the presumptive Democratic nominee for president, described the killing of George Floyd, a black man who died after police pinned his neck to the ground for several minutes, as an "act of brutality."

"Once again — the words 'I can't breathe.' An act of brutality so elemental, it did more than deny one more black man in America his civil rights and his human rights. It denied his very humanity. It denied him of his life," Biden said Friday.

President Trump on Friday evening struck a more somber tone talking about the death of George Floyd and recent protests in Minneapolis. The comments at the White House came after a day of criticism over a tweet that referred to protesters there as thugs and prompted a warning from Twitter, which said the president glorified violence.

President Trump wants an arena full of tens of thousands of excited Republicans in Charlotte this summer for the party's national convention. But the coronavirus is causing a lot of uncertainty, and North Carolina Democratic Gov. Roy Cooper hasn't been able to make assurances that such a gathering will be possible in August.

Louis DeJoy, a North Carolina businessman who has given millions of dollars to the Republican Party, including the Trump campaign, has been named the nation's new postmaster general.

The U.S. Postal Service's Board of Governors made the announcement Wednesday night.
