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."

What they're saying: Rep. Ted Lieu has called for new legislation requiring a psychiatrist to be present at the WH. And last week, Rep. Zoe Lofgren introduced a congressional resolution urging Trump to undergo medical and psychiatric evaluations. Rep. Jackie Speier has also called for invoking the 25th Amendment, which enables the vice president and Cabinet to remove a president who is unable to fulfill his duties.

Some Democrats are concerned their moves could backfire, and fear that igniting the mental health debate could alienate them. Veteran strategist Roger Salazar, former spokesman for Bill Clinton and Al Gore said, "It doesn't take a rocket scientist to figure out Trump is out of his mind. There's no question he is unfit for office. But I'd rather Democrats focus our energies on beating him and his allies at the ballot box."

Former White House press secretary Sarah Huckabee Sanders will announce Monday that she's running for governor of Arkansas.

The big picture: Sanders was touted as a contender after it was announced she was leaving the Trump administration in June 2019. Then-President Trump tweeted he hoped she would run for governor, adding "she would be fantastic." Sanders is "seen as leader in the polls" in the Republican state, notes the Washington Post's Josh Dawsey, who first reported the news.

Coronavirus has inflamed global inequality

History will likely remember the pandemic as the "first time since records began that inequality rose in virtually every country on earth at the same time." That's the verdict from Oxfam's inequality report covering the year 2020 — a terrible year that hit the poorest, hardest across the planet.

Why it matters: The world's poorest were already in a race against time, facing down an existential risk in the form of global climate change. The coronavirus pandemic could set global poverty reduction back as much as a full decade, according to the World Bank.
