Newt Gingrich says Trump has a 'compulsion to counterattack'

"I don't think that tweet helped him," Gingrich told Raddatz on "This Week."

But, the former GOP House Speaker added, Trump "is infuriated, and legitimately, in my judgment, by this whole Russian baloney.”Gingrich was referring to a tweet by Trump on Friday that appeared to confirm that the president is under investigation in the Russia probe.

The president seemed to be referring to Deputy Attorney General Rod Rosenstein, who wrote a memo detailing what he saw as concerns about Comey's leadership of the FBI immediately prior to Trump's firing him on May 9.

In the letter to Comey informing him of his dismissal, the president said he was acting on a recommendation from Rosenstein. A few days later, however, in a May 11 interview, Trump told NBC News he was thinking of the Russia investigation when he ultimately made the decision to dismiss Comey.

Referring to an ABC News report that Rosenstein has said he may need to recuse himself from having authority over the Russia probe, Raddatz asked Gingrich if the deputy attorney general should take that action.

"No," Gingrich said. "I think this whole game of recusal now is -- this is a nightmare."
