Former Vice President Joe Biden's 2020 campaign seized on video of world leaders seemingly chuckling about President Trump at the NATO summit, including the hot mic clip, in an ad saying the "world is laughing at" Trump.

The big picture: Biden's video also features a clip from Trump's 2018 speech before the UN during which he was met with laughter when he said his administration "has accomplished more than almost any administration in the history of our country."

What he's saying: Trump has yet to comment on Biden's video, but he called Canadian Prime Minister Justin Trudeau "two-faced" for apparently gossiping about him to British Prime Minister Boris Johnson and French President Emmanuel Macron and Queen Elizabeth II's daughter, Princess Anne, on a hot mic at Buckingham Palace.

Public schools in Los Angeles and San Diego, the two largest public school districts in California, will not be sending children back to campuses next month and will instead administer online classes due to concerns over the ongoing threat of the coronavirus.

Why it matters: The two districts, which together enroll about 825,000 students, are the largest in the country thus far to announce that they will not return to in-person learning in the fall, even as the Trump administration aggressively pushes for schools to do so.
