Sen. Cory Booker (D-NJ) and other Democrats on the Senate Judiciary Committee are planning to ask President Trump's Supreme Court nominee Brett Kavanaugh to not participate in future cases involving Special Counsel Robert Mueller's investigation into Russian collusion spanning from the 2016 election, if confirmed, Politico reports.

The backdrop: This comes in response to past remarks Kavanaugh made that a sitting president should be exempt from civil lawsuits or criminal investigations. And as Politico notes, the high court could rule on matters related to the special counsel's probe. Senate Majority Whip John Cornyn (R-Tx.) called Democrats' call for recusal "ridiculous."
