Fox News host Bret Baier pushed acting Homeland Security Secretary Kevin McAleenan on Sunday amid reports 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 deal with Mexico to avert U.S. tariffs in exchange for tighter border security is largely the same as one that had previously been agreed upon.

"How much of this is new?" Baier asked McAleenan after Trump denied a New York Times report that Mexico had agreed to take action at the border months ago.

“Your predecessor, Secretary [Kirstjen] Nielsen, testified that these things were happening to the House Judiciary Committee. There were talks about moving national guard troop to the southern border with Guatemala. You're saying this is different than that?” Baier asked.

McAleenan, however, claimed that the deal announced by Trump was "very different" than what had previously been discussed.

"The president put a charge in this whole dialogue with Mexico with the tariff threat, brought them to the table. The foreign minister from Mexico arrived within hours. He arrived the next day with real proposals on the table," McAleenan said.

Trump tweeted earlier Sunday that The New York Time article was "another false report."

On Friday, the president announced that 5 percent tariffs, which were set to take effect on Monday and incrementally increase until reaching 25 percent, would not go into effect because of concessions from Mexico on border security.
