In the three weeks since Trump won the election, he has dropped or leaned away from a number of key campaign promises, puzzling some of his supporters. Appointing a special prosecutor to investigate his former rival Hillary Clinton is no longer a top priority for Trump, who sympathetically said Clinton already "went through a lot." He said he is now open to amending the Affordable Care Act instead of fully repealing it. And several of his Cabinet picks are longtime players on Wall Street or in Washington -- the so-called "swamp" that Trump has pledged to drain.
