Sen. Lindsey Graham: Trump Could 'Go Down'

South Carolina Sen. Lindsey Graham said on Sunday that President Trump's inappropriate discussion of the investigation into his campaign's potential collusion with Russia was "frustrating."

"Here's what's so frustrating for Republicans like me: You may the first president in history to go down because you can't stop inappropriately talking about an investigation that, if you just were quiet, would clear you," Graham said on CBS's Face the Nation.
