What we're watching: Abortion rights the focus of Trump's SCOTUS pick

As President Trump gears up to announce his nominee to replace Anthony Kennedy on the Supreme Court, the court's 1973 decision in Roe v. Wade, which overturned many state and federal restrictions on abortion rights, is in the spotlight.

The big picture: There's debate about whether the next Supreme Court justice would vote to overturn Roe, given the court's shift to a stronger conservative majority. Republican Sen. Susan Collins (Maine), who is pro-choice and one of the Senate's key swing votes in the SCOTUS confirmation process, told CNN's Jake Tapper that she would not vote for a nominee who "demonstrated hostility" toward the decision.
