'He's been compromised': Rob Reiner explains to 'AM Joy' why Trump is a 'national security issue'

Director Rob Reiner said President Donald Trump's inaction on possible Russian interference in the 2016 election -- and in next year's midterms -- was evidence he'd been "compromised."

Reiner, who recently formed the Committee to Investigate Russia information clearinghouse, told MSNBC's "AM Joy" that foreign attempts to disrupt American elections was a an issue the president should be taking seriously.

"This is a national security issue," Reiner told host Joy Reid. "Whenever our country's been attacked, whether it's Pearl Harbor or 9/11, we've always come together. This is the first time we are not doing anything to protect ourselves because we have a president who -- I think there's a confluence of things here, but he's basically somebody who has been compromised and who's worried about the legitimacy of his election."

Reiner suggested the president was violating his oath of office by neglecting the possibility of Russian interference.

"He is not taking a position to do what the president is supposed to do, which is to make us safe," Reiner said. "We are not being made safe. There's no emphasis on trying to bolster our national security in 2018 and 2020."
