Rep. Adam Schiff, the top Democrat on the House Intelligence Committee, voiced support for President Trump's national security adviser on Sunday, saying that H.R. McMaster is likely under fire from Russian social-media campaigns intended to sow discord within the administration.

"I think it's indicative of the idea that the Russians don't particularly like Gen. McMaster," Schiff, D-Calif., stated on CNN's "State of the Union." "They may not like his policies, what he's advocating with the administration. Or they may just be seeking to sow further discord among Trump administration officials, feeling that that would weaken the administration."

In the past week, McMaster faced a sustained effort by some right-of-center media outlets and social media campaigns either aiming to influence McMaster's policies, or outright angling to have him fired, with the hashtag #firemcmaster forcefully inserting itself into the dialogue.

A New York Times report claimed that at least 600 of the Twitter accounts that were pushing that hashtag, however, were "bots" – accounts set up to advocate and advance the influence of Russia within the American political dialogue.

"I think Gen. McMaster is a good man," Schiff said. "I met him in Afghanistan when he was working there. I think he's a straight shooter, and I that hope the president will ignore those voices. He is one of [the] people, frankly, one of the few people that people on both sides of the aisle have confidence in that are within this administration."
