Former New Jersey Gov. Chris Christie is taking to TV.

Christie, who left office earlier this month, has been hired by ABC as a political contributor, according to the Associated Press.  He made his first appearance in the new role during Tuesday's "Good Morning America," ahead of President Trump's first State of the Union address,

Before a four-minute-long appearance, co-anchor George Stephanopoulos described the former Republican governor as Trump's "friend and adviser."

The two touched on a wide range of topics, including former FBI deputy director Andrew McCabe, the release of a Russia-probe memo and talk of a sit-down between President Trump and special counsel Robert Mueller.

Christie said Trump should not be interviewed by Mueller.

"I don't think there's been any allegations, credible allegations, against the president of the United States and I don't think the president of the United States, unless there are credible allegations, which I don't believe that there are, should be sitting across from a special counsel," he said during the appearance. "The presidency is different."

Christie was brought on board at ABC due to his relationships with the White House and will assist in the network's coverage of the upcoming midterm elections, NJ.com reported Monday.

Stephanopoulos said Christie also were slated to appear on air later Tuesday night as part of the network's continued State of the Union coverage.

Christie served as New Jersey's governor for two terms. Democrat Phil Murphy was sworn into office earlier this month. When he left office, Christie said he was taking his time considering offers, but wouldn't comment on New Jersey affairs going forward.
