Republican National Committee (RNC) spokeswoman Kayleigh McEnany on Friday said that President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE's proposed border wall will be built if Republicans increase their majorities in the House and the Senate in November's midterm elections.

"If, in fact, Republicans win the House and the Senate, do you believe the wall will get built?" Hill.TV's Buck Sexton asked McEnany on "Rising."

"I do," McEnany said. "I think we have to pick a few more Senate seats, and I think it's possible. Obviously, hold on to the House as well."

Trump has pushed for stricter immigration laws since the start of his presidential campaign in 2015, which include constructing a border wall along the U.S.-Mexico border.

The president threatened a government shutdown earlier this week in order to secure increased border security measures.

"If we don't get border security after many, many years of talk within the United States, I would have no problem doing a shutdown," Trump said on Monday.

"I have no red line, unlike President Obama," he continued. "I just want great border security."

McEnany emphasized the importance of the border wall and immigration in pushing voters to the polls, saying it was one of the top three issues for the Republican base.

"This is a battle of the bases. We need people to tout base issues," she said.

"I was talking to one of our interns, and she said do you know one of the most emailed things I get at the RNC is 'when are we going to build the wall?' Because that really motivates our base, building the wall, immigration. That's a lightning issue. It's in the top three of concerned issues."
