Sen. Chris Murphy (D-CT) said Thursday that the Democratic Party has trouble making the case that President Donald Trump is corrupt because of the past abuses within its ranks.

“When we talk about Trump’s corruption, we’re not terribly credible because the American public looks at Democrats and assumes that we’re just as corrupt,” Murphy said at a Center for American Progress event in Washington D.C. “And we obviously have had some pretty high-profile problems in our party in the last decade.”
