Homeland Security director John Kelly said President Trump “will be insistent” that Congress fund his campaign promise of building a border wall along the Mexican border as a showdown over a possible government shutdown looms.

“I think it goes without saying that the president has been pretty straightforward about his desire and the need for a border wall. So I would suspect, he’ll do the right thing for sure, but I would suspect he will be insistent on the funding,” Kelly said on CNN’s “The State of the Union,” in an interview that aired on Sunday.

Trump’s request for $1.4 billion to fund a wall on the southern border has been met by skepticism by some lawmakers as Congress rushes to pass a stopgap spending bill to keep the government operating past

Friday, April 28, and as the president marks his first 100 days in office on Saturday.

Sen. Dick Dubin called Trump’s insistence on building a wall “a political stunt, an obsession” that could lead to a government shutdown.

“To think that he would consider shutting down the gover nment of the U nited S tates of A merica over this outlandish proposal of a border wall ,” said Durbin, (D-Ill.) on CNN on Sunday. “T hat would be the height of responsibility. He does not want that to define his first 100 days . ”

Last week, an survey showed lawmakers representing districts in states along the border – Texas, New Mexico, Arizona and California – do not back Trump’s proposal.

Asked why the nine House members and eight Senators opposed it, Kelly chalked it up to politics.

“Don’t know. I guess it’s politics ,” said Kelly on CNN. “I would just offer to you many of these issues would go away if the same people that we’re talking about the legi slators in Washington would take a

really long hard look at immigration and immigration laws and do what is necessary to solve the problems. “
