President Donald Trump once succinctly summed up his two-part defense on his campaign’s contacts with Russia during the 2016 election in an interview with the New York Times: “There is no collusion, and even if there was, it’s not a crime.” In recent days, the first half of that defense has started to look shakier. Trump’s own lawyer, Rudy Giuliani, seemed to indicate that more evidence may come out, telling CNN that he “never said” there was no collusion between the campaign and Russia, only ruling out direct involvement with the president.
