Brett Kavanaugh, U.S. Supreme Court associate justice nominee for U.S. President Donald Trump, right, and Senator Susan Collins, a Republican from Maine, smile during a meeting on Capitol Hill in Washington, D.C., U.S., on Tuesday, Aug. 21, 2018.

Supreme Court nominee Brett Kavanaugh thinks the landmark Roe v. Wade ruling on abortion rights is settled law. That's according to Sen. Susan Collins, a Republican senator from Maine who met for two hours with the judge on Tuesday.

Collins, who supports abortion rights, says she talked "at great length" with Kavanaugh about the application of established precedent to abortion cases. She says they also discussed executive power and his judicial philosophy, among other subjects.
