Trump's re-election campaign sent a memo to television producers on Monday instructing them to "employ basic journalistic standards when booking" six current or former government officials that the campaign said "made outlandish, false claims, without evidence" while on air.

The memo names:

Sen. Richard Blumenthal, D-Conn.

Rep. Jerry Nadler, D-N.Y., the chair of the House Judiciary Committee

Democratic National Committee Chairman Tom Perez

John Brennan, the former director of the Central Intelligence Agency

Rep. Adam Schiff, D-Calif., the chair of the House Intelligence Committee

Rep. Eric Swalwell, D-Calif., who has floated a potential bid for president

In a statement, Swalwell said that the "only person who has been caught lying about Russia is Donald Trump."

"If he thinks I've made a false statement, he can sue me. And I'll beat him in court," Swalwell said.

A spokesman for Blumenthal dismissed the Trump campaign's memo. "Senator Blumenthal has never claimed that Special Counsel Mueller could clear the incredibly high bar to bring charges of criminal conspiracy in this case," the spokesman said. "But there is obvious, significant evidence of Trump campaign collusion already in the public realm."

The others targeted in the memo either declined to comment or did not respond to a request for comment from CNBC.
