Incoming White House Chief of Staff Reince Priebus on Wednesday said a report raising questions about President-elect Trump’s relationship with the Kremlin is just “offensive crap.”

Speaking on NBC, Priebus said the fact that BuzzFeed published an unverified 35-page document makes the website itself “not credible.” BuzzFeed published the document that’s reportedly been floating around the upper echelons of the U.S. government in order to let the American people decide what to believe.
