President Donald Trump's attorney, Rudolph Giuliani, asserted Monday that "collusion is not a crime." "I have been sitting here looking in the federal code trying to find collusion as a crime," Giuliani said in an interview on "Fox & Friends." "Collusion is not a crime." The president has repeatedly asserted that there was "no collusion" between his campaign and Russia during the 2016 U.S. presidential election. The president took to Twitter to repeat the claim, as recently as Sunday.
