White House press secretary Sean Spicer defends Trump's 'significant' work in 100 days

They are "very proud" of their work, Sean Spicer says.

"When you look at the totality of what we've accomplished ... it is unbelievable what he has been able to do," Spicer said at the day's press briefing.

Spicer said that "you can cherry-pick" issues "to look and pick out two or three things" that were not completely addressed during the first 100 days but argued that it would be an inaccurate picture of the administration's work.

"It's easy to nitpick," he said.

"We are very proud, and the president is very proud of what he's been able to accomplish in the first 100 days ... but we also want to start talking about the next 100 days," Spicer said.

Spicer also said that while he "can't guarantee" a government shutdown will be avoided, he doesn't think it's going to happen.

"I can't guarantee," he said of ongoing budget negotiations. "But I think that the work that [Office of Management and Budget] Director [Mick] Mulvaney and others have made in this front and negotiations have been very positive. They feel very confident that won't happen.

"We feel very confident that the government is not going to shut down," he said.
