Sen. Marsha Blackburn (R-Tenn.) said on Wednesday that Democratic senators running for the party’s 2020 nomination should recuse themselves from taking part in President Trump’s impeachment trial.

“Tomorrow, one hundred United States Senators will be sworn in to serve in the impeachment trial of President Donald Trump. Four of those Senators must recuse themselves for their unparalleled political interest in seeing this President removed from office,” Blackburn said in a statement.

She added that Sens. Bernie Sanders (I-Vt.), Amy Klobuchar (D-Minn.), Michael Bennet (D-Colo.) and Elizabeth Warren (D-Mass.) “cannot sit in judgment of the very President they seek to replace.”
