After President Trump alleged Tuesday that California Sen. Adam Schiff had committed mortgage fraud, Schiff dismissed the claim as a 'baseless attempt at political retribution.'

President Trump accused Sen. Adam Schiff (D-Calif.) of mortgage fraud on Tuesday, calling Schiff a "scam artist" who "needs to be brought to justice." Why it matters: Trump's call for Schiff to be prosecuted is part of a larger pattern of the president seeking retribution against Americans who have spoken out against him.
