CNN's John King on Wednesday expressed shock that no one has been able to convince President Donald Trump to stop tweeting unfounded conspiracy theories about MSNBC host Joe Scarborough murdering a staffer 20 years ago.

During an interview with David Gergen, King said it was particularly jarring to see Trump, in the middle of a pandemic that has killed 100,000 Americans, to be tweeting things that "if I tweeted them, we would be fired in a snap."

Gergen then looked back at how past presidents have handled tragedies, and he said Trump pales in comparison to all of them.

"This should be a week of national mourning, to have 100,000 deaths, the number we'll reach in the next two or three days, and the country is saddened by that," he said. "Traditionally, presidents bring us together for occasions like this. They brought comfort, they met privately with the families of the victims and cheered people up... and here now, we have completely the opposite. It's very, very sad."

"The View" co-host Meghan McCain called for charges against the Minneapolis police officers who killed George Floyd.

The four officers lost their jobs over the killing, which prompted widespread protests that were met with tear gas and other violent tactics from police.

"There was huge amounts of protesters that took to the streets last night, and I think people are sitting in their homes and seeing what is blatantly a murder of a man on camera, and George Floyd, I watched the entire video," McCain said. "I know we didn't want to show the entire thing, but it's very graphic. It's very violent."
