In a call Tuesday to former White House chief strategist Stephen Bannon, Trump put blame on Kushner for the part he took in choices to fire former national security adviser Michael Flynn and former FBI director James Comey, Vanity Fair reported.

Roger Stone, a longtime Trump ally, also recently said Kushner wasn't giving Trump good advice — a sentiment which Trump reportedly agreed with, according to someone familiar with the conversation.

Sam Nunberg, a former campaign aide to President Trump who was fired, echoed the statement.

“Jared is the worst political adviser in the White House in modern history,” Nunberg said.

“I’m only saying publicly what everyone says behind the scenes at Fox News, in conservative media, and the Senate and Congress."

Trump has also reportedly complained about Mueller's investigation being allowed to continue.

Trump has repeatedly lashed out on Twitter over the appointment of a special counsel to probe Russia's election meddling and the possibility that Trump campaign staff colluded with the Kremlin.

On Monday, his former campaign chairman Paul Manafort was charged with nine counts, including conspiracy against the United States and money laundering relating to his work for a pro-Russia political party in Ukraine. His longtime deputy, Richard Gates, was charged as well. Both pleaded not guilty.

Trump on Monday insisted his team did not collude with Russia, adding that alleged crimes committed by Manafort occurred "years ago."
