The Democrat will meet with Judge Brett Kavanaugh on Tuesday. She faces a tough battle for re-election this year in a state Trump won by 19 points.

McCaskill has said she wants to know Kavanaugh’s opinion on the 2010 U.S. Supreme Court’s Citizens’ United decision that allowed corporate spending in elections.

McCaskill also says she wants to know how Kavanaugh feels about a Republican-led lawsuit to overturn former President Barack Obama’s health care law. And she says she’s interested in Kavanaugh’s views in cases of “the little guy versus the big guy.”

Republicans have been pressuring Democratic senators up for re-election this year to meet with Kavanaugh, particularly in states that Trump won.
