Democrats consider Donald Trump's tapping of Sen. Jeff Sessions as the nation's next attorney general "a big threat" to the legacy of current Attorney General Loretta Lynch and her predecessor Eric Holder, attorney and former Trump adviser Sam Nunberg tells Newsmax TV.

"[Sessions] is going to be supported by all the Republicans and the good news is Chairman [Chuck] Grassley of the Judiciary Committee has already come out in support of him. Now obviously … for the left and for the Democrats … he's a big threat to them," Nunberg said Friday to J.D. Hayworth on "America Talks Live."

"He's going to destroy the legacy of Eric Holder and Loretta Lynch because, as you know, the role of the attorney general is to be the chief law enforcement officer of the United States, and unlike his predecessors he actually believes in law enforcement.

"And I do think that this is somewhat of a threat, obviously, to [President Barack] Obama and his legacy and [Sessions is] going to be hit up by MSNBC, he's going to be hit by The New York Times, but at the end of the day he's going to get confirmed and he's going to do an excellent job."

Nunberg said that with Sessions, an Alabama Republican, as attorney general, "we're going to come back to a law and order administration."

"I'm happy President-elect Trump made him the nominee because there was a lot of talk about possibly others trying to get this position, including Chris Christie [the New Jersey governor and axed Trump transition-team head]."

Nunberg said he is also impressed at Trump's choice of retired Army Lt. Gen. Michael Flynn to be the next national security adviser.

"He's been a trusted adviser to President-elect Trump … and he was there early on. He was giving President-elect Trump briefings by around August 2015, he's been very supportive, he campaigned for him, and he really went outside the norms for a general," Nunberg said.

"He ran the defense intelligence agency and the Obama administration basically fired him because he did not like the way his intelligence was being processed by [James] Clapper and they were misinforming the public on ISIS.

"He truly understands the Islamist threat around this country and I think he'll be a tremendous asset for President-elect Trump."

As well, Nunberg is comfortable with Sen. Mike Pompeo, a Kansas Republican as the nation's next CIA chief.

"He also has a very good experience as a CEO of an aerospace company, I believe, and I'm sure he has, during his private sector experience, dealt with the CIA," Nunberg said.

"This is an appointment that has gotten recommendations or support on both sides of the aisle, actually … It's actually very good. It's sort of like draining the swamp here."
