President Donald Trump said he would nominate Judge Brett Kavanaugh for a seat on the U.S. Supreme Court, a choice that could create the most conservative court in generations and threaten landmark rulings including the Roe v. Wade abortion rights decision.

If confirmed by the Senate, Kavanaugh would fill the seat of retiring Justice Anthony Kennedy, a swing vote who sometimes sided with the court's liberals in key cases. Trump wants to leave an enduring mark on the court, giving it a solid five-justice conservative majority for the foreseeable future.

"I do not ask about a nominee's personal opinions," Trump said Monday night. "What matters is not a judge's political views but whether they can set aside those views to do what the law and the Constitution require."
