A turning point for the Trump campaign’s legal efforts came on Nov. 13, when its core team of professional lawyers saw the writing on the wall. The U.S. Court of Appeals for the 3rd Circuit in Philadelphia delivered a stinging defeat to Trump allies in a lawsuit trying to invalidate all Pennsylvania ballots received after Election Day.
