Rudy Giuliani on Friday praised John Bolton as a potential pick for secretary of State while pushing back on the possible selection of Mitt Romney.

Shortly after Trump's transition team announced Giuliani had withdrawn himself from consideration for the position, the former New York City mayor echoed concerns from Trump loyalists Newt Gingrich and Mike Huckabee about Romney.

"I thought Mitt went over the line in the things that he said about Donald Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE," Giuliani said during an interview with Fox New's Neil Cavuto.

"The president-elect is going to make his decision, I will support that decision, but you know my advice would be Mitt went just a little too far. You can make friends and make up, but I would not see him as a candidate for the Cabinet."

When asked who he thought would be the best choice for secretary of State, Giuliani said that he preferred Bolton, the former U.S. ambassador to the United Nations.

“John [Bolton] would probably be my choice. I think John is terrific,” Giuliani said.

Giuliani's comments came shortly after Trump's transition team announced he had withdrawn himself from consideration for a position in Trump's administration.

Giuliani said the decision to not join the Trump administration was made Nov. 29, but "a number of different people" wouldn't accept it then. He indicated Friday he wasn't interested in another position.

"Honestly, the other positions I didn’t have an interest in," he said on Fox. "That was the only one I had any real interest in."

The news Friday came amid continued jockeying for the position of secretary of State.

Two Trump transition team sources told The Wall Street Journal that Rex Tillerson, the chief executive of Exxon Mobil, was the leading candidate to become the nation's next top diplomat.

But several other potential picks are reportedly still in the running for the position, including Romney and retired Gen. David Petraeus. Romney, the 2012 GOP nominee, was a vocal critic of Trump's candidacy, but has met twice with the president-elect to discuss foreign policy.

Giuliani spoke about the selection process Friday, saying it had become "very confusing" and "very difficult" for Trump.

"My desire to be in the Cabinet was great, but it wasn’t that great and he had a lot of terrific candidates and I thought I could play a better role being on the outside and continuing to be his close friend and advisor," Giuliani said on Fox.

According to Giuliani, the last conversation he had with the president-elect prior to his withdrawal from consideration was about the announcement and whether it was a proper time to release a statement.

“It was, 'This is a good time to do it, they’re down to the last two, three four.' So, it made sense to just get out of the way,” the former mayor said. "I’m a very happy man, I’m very happy with what I do."
