Stephen Miller held a closed-door meeting with House Republicans to discuss Trump’s immigration reform.

President-elect Trump’s top immigration and border aide spoke during an hour-long meeting with House Republicans on Wednesday.

Lawmakers leaving the room hailed Stephen Miller, who has been tapped to be the new Trump administration’s homeland security adviser, as a brilliant policy mind.

Two sources involved in the discussions told Fox News Digital that Miller said there was a need to increase Immigration and Customs Enforcement (ICE) manpower, which is noteworthy given Trump’s promise to enforce mass deportations when he returns to office.

Miller also discussed ways to cut federal funds to sanctuary cities and states, a flow of money Republicans have previously vowed to target if they take control of power plants in Washington.

The strategy meeting comes as congressional Republicans prepare for major conservative policy overhauls in the budget reconciliation process. By lowering the threshold for passage in the Senate from 60 votes to 51, the reconciliation would allow the party that controls Congress and the White House to pass a wide range of policy changes — as long as they don’t touch on the budget and other fiscal issues.

The sources told Fox News Digital’s Miller that part of the meeting focused on which border and immigration policies could be included in the reconciliation package and what funding Congress should appropriate.

The sources said Miller told Republicans that the incoming Trump administration’s president-elect’s border and immigration goals “probably won’t get many Democratic votes” and that “those more controversial things should be reconciled.” Additional bilateral initiatives may be passed through the formal process, the sources added.

A House GOP lawmaker told Fox News Digital that he understood Congress would follow Trump’s lead.

“I think we’re going to see a lot of executive orders early on, and that will be important to distinguish if we have to legislate,” the lawmaker said.

A source in the department said Miller emphasized the importance of messaging, saying, “If we don’t get our message across to the American people, it doesn’t matter.”

Rep. Ralph Norman, RS.C., told Fox News Digital Miller had discussed “low-hanging fruit” that Trump could deal with through an executive order, citing “deportation” as an option.

“The tax stuff, that’s going to take a while,” Norman said.

Rep. Mark Alford, R-Mo., declined to provide details about the meeting, but told Fox News Digital that the discussion focused on “illegal immigration and how to stop it … to bring common solutions to the program.”

“I had two questions about the cost to American taxpayers if we don’t return the 12 million illegal aliens that the Biden administration has brought into our country,” Alford said.

Miller declined to answer reporters’ questions as he left the room.

He was invited to address the Republican Study Committee by Rep. August Pfluger, R-Texas, the House GOP’s largest caucus, which serves as a conservative think tank for the rest of the Republican conference.

House GOP leaders, such as Speaker Mike Johnson, R-La., were not present or expected.

Rep. Kevin Hearn, R-Okla., the group’s former chairman, said during the meeting that there was “nothing new” and an opportunity for Trump aides to address the House GOP.

Trump and his aides have already paid close attention to congressional Republicans.

Several incoming White House aides meet regularly with top GOP lawmakers. Trump invited several groups of House Republicans to Mar-a-Lago last weekend.
