Sen. Richard Blumenthal says President Trump has become the “puppet” of outside conservative groups in the selection of the next U.S. Supreme Court justice. “The president’s outsourced this decision to the Federalist Society and the Heritage Foundation,” Mr. Blumenthal said Sunday on ABC’s “This Week.” “It is extraordinary. I was a law clerk to Justice Blackmon. I’ve argued cases before the Supreme Court—four of them. I’ve never seen a president of the United States in effect make himself a puppet of outside groups and choose from a group of right-wing fringe ideologues that are prepared on this list.”
