Retired 4-star admiral William McRaven resigned from the Pentagon's Defense Innovation Board last month, just 4 days after issuing a public critique of the president in the form of an op-ed he penned after Trump revoked John Brennan's security clearance, Defense News reports.

One key quote: In the op-ed, McRaven, former head of the Special Operations Command, wrote, "Through your actions, you have embarrassed us in the eyes of our children, humiliated us on the world stage and, worst of all, divided us as a nation. If you think for a moment that your McCarthy-era tactics will suppress the voices of criticism, you are sadly mistaken. The criticism will continue until you become the leader we prayed you would be."

"I'm asthmatic," said Stone, 67. "Sending me to a prison where I could not be socially distanced ... would, I think, be a death sentence."

Facebook last week took steadily intensifying heat from fleeing advertisers and boycott leaders and received a big thumbs-down from its own civil-rights auditors. Its response, essentially: We hear you, but we'll carry on.

The big picture: Early on in Facebook's rise, CEO Mark Zuckerberg learned to handle external challenges by offering limited concessions and soothing words, then charging forward without making fundamental changes.
