Biden then scoffed at Trump for
comparing his legal troubles to the political persecution of Navalny, an outspoken Putin critic who died in a Russian prison last week. During a Fox News town hall Tuesday, Trump described the $350 million business fraud judgment he faces as “a form of Navalny.”

Biden called Trump’s remarks unhinged. “If I stood here 10 to 15 years ago and said all this, you’d all think I should be committed,” he said.

Trump’s campaign clapped back, saying Biden is the one who belongs in a psychiatric facility.

“Crooked Joe Biden is saying the quiet part out loud, he should be committed because of the total failure he has been for this country, and the misery and destruction he has caused,” a Trump spokesperson told POLITICO in a statement.

Biden also said that when he meets with other heads of state they quietly tell him they’re rooting for his reelection.

“As I walk out of meetings, a head of state will find an excuse to come up close … and say, ‘You’ve got to win.’ Not because I’m so special. ‘You’ve got to win because my democracy is at stake if the other guy wins.’ Nine heads of state have done that with me,” Biden said.

After condemning Trump, Biden moved on to the broader Republican Party, saying the GOP has lost their “American moral center.”

He crowned Rep. Nancy Pelosi, who was in attendance at the San Francisco event, the “best speaker there has ever been.”

The president eventually circled back to climate change, saying he has a long personal history with environmental issues since his childhood in Scranton, Pennsylvania where the family home had a coal furnace. He attributed his asthma to his upbringing in a heavily polluted Delaware town.

But, Biden said he’s optimistic about his administration’s environmental agenda.

“We don’t have to convince people anymore there is climate change,” he said.
