(NBC News) President Donald Trump spent Saturday morning on Twitter responding to a New York Times report that the FBI investigated whether he worked on behalf of Russia against U.S. interests and if the president could be a national security threat.

Over a series of five tweets — beginning at 6:05 a.m. and wrapping up at 8:20 a.m. — Trump attacked the New York Times, the FBI, former FBI Director James Comey, Hillary Clinton, Robert Mueller and a handful of others in response to a story that looked into a counterintelligence investigation of the president and his decision making surrounding Russia.

“Wow, just learned in the Failing New York Times that the corrupt former leaders of the FBI, almost all fired or forced to leave the agency for some very bad reasons, opened up an investigation on me, for no reason & with no proof, after I fired Lyin’ James Comey, a total sleaze!” the president wrote on Twitter.
