Trump's stability has been called into question in recent weeks, most notably by GOP Sen. Bob Corker and former Director of Intelligence James Clapper. But now, California Dems are seizing on the opportunity to magnify an issue that until recently has received little pickup: the notion that Trump may not be mentally fit for office, per Politico.

"[Trump] has demonstrated that his mental capacity and his erratic behavior are issues we need to be concerned about for our national security," Rep. Jackie Speier told Politico. "And I think I'm not the first person that's talked about it. I'm just the first person that's been public about it."
