Newt Gingrich told ABC News that his greatest worry is that President-elect Donald Trump and his team will “lose their nerve” once in office.

Said Gingrich: “Look, they’re going to arrive in Washington, and for them to be successful they have to stake out positions that DNC Chairwoman Donna Brazile will not like and the left will hate. I’m worried that when they realize how big the problem is, that they decide that they’re just going to do the best they can and give in.”

He added: “You’re going to have the government employees going crazy about civil service reform. You’re going to have the teachers union going crazy over school choice. And these are pretty nonnegotiable. I mean, if you’re serious about school choice, there is no agreement with the teachers union.”

“The Constitution gives the president of the United States an extraordinarily wide grant of authority to use the power of the pardon. I’m not saying he should. I’m not saying he will. It also allows a president in a national security moment to say to somebody, go do X even if it’s technically against the law and here’s your pardon because I am ordering you as commander-in-chief to go do this.”

— Newt Gingrich, in an interview with NPR.

“In the case of the president, he has a broad ability to organize the White House the way he wants to. He also has, frankly, the power of the pardon. It’s a totally open power. He could simply say, ‘Look, I want them to be my advisers. I pardon them if anyone finds them to have behaved against the rules. Period. Technically, under the Constitution, he has that level of authority.”
