President Trump tore into The Washington Post in a series of tweets on Monday evening after the paper reported that his administration planned to end a program that provides support to Syrian rebels.
"Is Fake News Washington Post being used as a lobbyist weapon against Congress to keep Politicians from looking into Amazon no-tax monopoly?" Trump tweeted Monday after returning from a speech in West Virginia.
Trump said the Post had "fabricated the facts" on stories about his Syrian rebel program and compared the paper to CNN, the most reviled news outlet at his White House and among his supporters.
The president has ratcheted up his attacks on the media in recent weeks as his administration has fought off further developments in the Russian controversy and a series of stories suggesting the West Wing is chaotic and mismanaged.
His new communications director, Anthony Scaramucci, has promised to de-escalate tensions between the White House and the press.
Trump has frequently gone after The Washington Post due to its relationship with Jeff Bezos, the founder of Amazon, although the two entities are unaffiliated.
