Republican Sen. Susan Collins of Maine downplayed the threat of a re-election challenge in 2020, as lawmakers' votes both for and against U.S. Supreme Court Justice Brett Kavanaugh in his contentious confirmation battle generate political backlash.
Collins, who voted for Kavanaugh in what she termed one of her hardest decisions ever, said in response to a question about a potential challenge from former U.S. National Security Adviser Susan Rice that she did what she thought was right. And besides, Collins said, Rice doesn't really reside in her state.
"Her family has a home in Maine, but she doesn't live in the state of Maine," Collins said on CNN's "State of the Union."
