Kelly: Trump campaign promises on border wall have 'evolved'

Lawmakers say Kelly told them Trump not "fully informed."

“He said the promises of the campaign and governance are two different things, you guys are all elected officials, you know that,” Rep. Raul Grijalva, D-Ariz. recalled Kelly telling the group.

Asked about the meeting in a Fox News interview, Kelly said Trump has changed the way he looks at issues since becoming president. "He has evolved in the way he's looked at things. Campaigns and governing are two different things," Kelly said.

Kelly said he told the lawmakers people say things "during the course of campaigns that may or may not be fully informed."

"There are places where geographically, a wall would not be realistic. There are other parts of the southwest border that are so wild and untamed that there is no traffic that goes through them, " he said on Fox. "There are other places we think about 800 miles additional wall to include the 600 that's already in place — the fencing — that would suffice."

Speaking to ABC News, Kelly said, "There are many places on the border that the professionals in Customs and Border Protection — men and women who work the border every day – can tell you exactly where they need more fencing or more barrier, and that’s what the president is seeking to do."

"That, combined with closing some of the loopholes, the draw if you will — because the average person that is coming to the U.S. illegally, whether they come by visa and overstay, or sneak through the southwest, they understand that our really, really ineffective immigration laws, essentially allow them to stay indefinitely," Kelly told ABC News.

Trump tweeted Thursday, "The Wall is the Wall, it has never changed or evolved from the first day I conceived of it."

One lawmaker questioned whether they can trust the White House to negotiate in good faith.

"Trump's a wild card," Grijalva, the Arizona Democrat, said. "There's no track record to be able to trust the White House on immigration."

Republicans who spoke with Kelly on Wednesday were more optimistic.

“The administration considers this one of its goals and I was very encouraged,” Curbelo said.

In another tweet Thursday, Trump reiterated his position on immigration reform saying, "If there is no Wall, there is no Deal!"
