The senator was discussing Trump's tweets on Sunday, in which he claimed that the FBI "broke into" his former lawyer Michael Cohen's office.

Democrat Sen. @maziehirono: “The President is always on the attack, especially when the walls are closing in … One hopes that the truth will prevail, but with the President, that’s really of little concern to him, apparently." pic.twitter.com/ScbxiOmQUk — The Situation Room (@CNNSitRoom) December 17, 2018

"[Trump] said the FBI just broke into Cohen’s office," Hirono said. "Nothing like that happened."

The FBI in April raided Cohen's home, office and hotel room, seizing troves of documents and computer files. The search warrants for the raids came in part based on a referral from special counsel Robert Mueller's office.

Cohen was sentenced last week to three years in prison for crimes he says he committed on Trump's orders.

"One hopes that the truth will prevail but with the president, that’s really of little concern to [Trump], apparently," Hirono said.

When reporters asked what Comey thought about Trump calling Cohen, who is now cooperating with federal investigators, a “rat,” Comey responded it “undermines the rule of law.”

“This is the president of the United States calling a witness who is cooperating with his own Justice Department a ‘rat,’ ” Comey said, suggesting people at home reflect on “where we have ended up."

Comey’s rebuke of the president and his fellow Republicans came after he returned to Capitol Hill on Monday for a final interview with GOP lawmakers before Democrats take control of the House.
