On MSNBC’s “The Briefing” Tuesday, Sen. Cory Booker (D-NJ) claimed President Donald Trump is the “most corrupt president in American history,” accusing him of corruption, crypto schemes, “monuments to his ego,” and kleptocracy.

Booker said many Republicans privately express disdain but stay silent publicly, warning they will be held accountable and predicting some are starting to show “wobbly knees.”
