Dems’ self-interest drives inquiry

Self-interest is at the heart of the Democrats’ impeachment inquiry into President Donald Trump’s actions. Given that we are heading toward an election year, I am wondering if the Democratic presidential candidates who are senators must recuse themselves from voting on the possible conviction of President Trump should impeachment lead to a trial in the Senate? After all, on a matter as important as removing a sitting president from office, we wouldn’t want to accuse Sens. Elizabeth Warren,

Bernie Sanders, Kamala Harris, Cory Booker, Amy Klobuchar or Michael Bennet of voting in their own self-interest, would we? — Richard P. Bail, Chicago
