Former Vice President Joe Biden on Sunday reached out to William McRaven — former commander of the U.S. Joint Special Operations Command, who oversaw the SEAL raid that killed Osama bin Laden — after McRaven dared President Trump to revoke his clearance, too.

The big picture: Since leaving office, the former vice president has maintained quiet contact with a range of former people he served with who have been dismayed by what they are seeing out there, according to someone close to Biden.

• Biden's rough message to McRaven: "It is presumptuous of me to say, but I’m so incredibly proud of you. I saw up close your physical courage, including your incredible calm during planning for the Bin Laden raid. As RFK said: 'Moral courage is the rarer commodity than bravery in battle.'"
• "I have never met anybody whose moral courage equaled their physical courage in your category. I’m proud to know you and be associated with you."
