New Jersey Gov. Chris Christie said Monday he urged President Trump not to give retired Lt. Gen. Mike Flynn a job in the White House.

"I think it's safe to say that General Flynn and I didn't see eye-to-eye," Christie told reporters during a news conference. "I didn't think that he was someone who would bring benefit to the president or to the administration, and I made that very clear to candidate Trump, and I made it very clear to President-elect Trump."

Christie, the former chairman of Trump's transition team, also said Flynn was "not my cup of tea."

"If I were president-elect of the United States, I wouldn't let General Flynn into the White House, let alone give him a job," the New Jersey governor said.

Despite Christie's warning, Trump selected Flynn to serve as his national security adviser. He fired him in February, though, after the retired general misled Vice President Mike Pence about conversations with Russian officials.

Flynn is under investigation for foreign lobbying, and federal prosecutors issued grand jury subpoenas to Flynn's business associates this month as part of the investigation into Russia' meddling in the 2016 election.

The New York Times reported last week Trump's transition team knew Flynn was under investigation, but the retired general was selected to serve as national security adviser anyway.

The Senate Intelligence Committee also issued a subpoena for documents from Flynn this month, but the retired general's attorneys told the committee Flynn will invoke his Fifth Amendment rights.

Flynn's lawyers said the "escalating public frenzy against him" and the decision by Deputy Attorney General Rod Rosenstein to appoint a special counsel to lead the instigation have created a "legally dangerous environment" for him to comply with the Senate Intelligence Committee's subpoena, the Associated Press reported.
