Former New York Southern District Attorney Preet Bharara made headlines Saturday when he was fired by the Trump administration after refusing to resign.

Attorney General Jeff Sessions this week called for the resignation of the 46 remaining Obama administration attorneys, including Bharara.

Former House Speaker Newt Gingrich joined "Fox & Friends Weekend" to talk about the Bharara's firing.

"President Trump is doing what President Trumps do," Gingrich said. "He is replacing the other team who opposed him with people who are on his side.

"This goes all the way back to Lincoln, to Andrew Jackson, Thomas Jefferson. The American people elect the president; they get to have the people they want in politically appointed offices."

Gingrich said asking the attorneys to resign continues the process of "draining the swamp."

He said the next phase in the process is identifying anyone totally opposed to the administration and figuring out how to fire or reassign them.

"I would go through the entire government," Gingrich said. "Abraham Lincoln fired 70 percent of the senior bureaucrats in the federal government. He had to get rid of Southern sympathizers and people in place willing to fight a civil war."

Gingrich concluded saying the bulk of money donated by federal officials was given to Democratic presidential candidate Hillary Clinton, meaning "there are a lot of folks out there who ain't for Donald Trump and are not going to help him."
