A day after firing FBI Director James Comey, President Trump told Russian officials visiting the White House he no longer felt "great pressure" because of the investigation into Russia's attempted meddling in the campaign, according to a report.

The New York Times on Friday reported that Trump said: "I just fired the head of the FBI. He was crazy, a real nut job. I faced great pressure because of Russia. That's taken off."

Trump, according to the report, also said: "I'm not under investigation."

The comments were made during Trump's May 10 meeting with several Russian officials. The New York Times said they obtained his comments from a document summarizing the meeting. The outlet said the document was based on notes taken from inside the Oval Office during the meeting, and a source read the quotations to them.

Trump met that day with Russian Foreign Minister Sergey Lavrov and Russian Ambassador Sergei Kislyak.

"The president has always emphasized the importance of making deals with Russia as it relates to Syria, Ukraine, defeating ISIS and other key issues for the benefit and safety of the American people," White House press secretary Sean Spicer said in response to the story. "By grandstanding and politicizing the investigation into Russia's actions, James Comey created unnecessary pressure on our ability to engage and negotiate with Russia. The investigation would have always continued, and obviously, the termination of Comey would not have ended it. Once again, the real story is that our national security has been undermined by the leaking of private and highly classified conversations."
