(CNSNews.com) – When asked by ABC News what he feared the most about the incoming Trump administration, former Republican House Speaker Newt Gingrich said it was that "they would lost their nerve.”

“When you look, Mr. Speaker, at the prospects for the Trump presidency, what do you fear the most?” ABC News chief White House correspondent Jonathan Karl asked Gingrich during a joint interview with former Democratic National Committee chair Donna Brazile that aired Sunday on ABC’s This Week.

“That they will lose their nerve,” Gingrich replied.

“Look, they're going to arrive in Washington, and for them to be successful, they have to stake out positions that Donna will not like and the Left will hate," Gingrich explained.

“And my deepest concern is they’re going to arrive and you’re going to have the Greens going crazy over the EPA [Environmental Protection Agency] and Interior [Department]. You’re going to have the government employees going crazy about civil service reform. You’re going to have the teachers’ unions going crazy over school choice.

“And these are pretty non-negotiable. I mean, if you’re serious about school choice, there is no agreement with the teachers’ unions,” Gingrich said.

“You’re worried they get squishy,” Karl suggested.

“I’m worried that when they realize how big the problem is, that they decide they’re just going to do the best they can and give in,” Gingrich clarified.
