House Republicans are set to be briefed by Secretary of War Pete Hegseth on Tuesday night regarding the White House's request for more than $350 billion in defense funding in the wake of the conflict with Iran, Speaker Mike Johnson, R-La., said.

"Some of this is transformational kind of funding that will help us change the dynamic of the Department of War and make it more efficient and effective," Johnson told reporters Tuesday. "It's already the greatest fighting force on the planet, not even close, but there are some ideas, a real vision on how to improve that even further, to bolster that."

But Johnson declined to disclose details of the funding request.

"You heard the president talk about how he wants to effectively double the funding for national defense," he said. "Look, we live in dangerous times. We're fighting communism on our own shores, and we're fighting evil terrorists and tyrants around the world. And we have to be able to protect our national security.

"So, this is not the place to get into the details of that. We're having a briefing tonight at the Pentagon with House Republicans where Secretary Hegseth and his team will go through and outline a lot of this. Much of that is going to be classified, of course."

Johnson added that lawmakers are determined to ensure the federal government lives up to its constitutional duty to protect Americans.

"By the way, in his State of the Union a few months back, the president asked that very important question of the body," Johnson said. "'Hey, stand and applaud if you think the number one job of the federal government is to protect American citizens and not illegal aliens.' Every Republican stood for long applause. Every Democrat sat scowling on their hands. That's everything you need to know.

"A picture is worth a thousand words, a video is worth even more. Go replay that. We're going to take care of national defense. We're going to meet our first priorities."

The meeting with Hegseth comes as Republicans finalize a framework for a third budget reconciliation bill of GOP priorities that can bypass a Democrat filibuster in the Senate. Johnson said "there will be markup this week" for the legislation.

"I was on the phone with [House Budget Committee] Chairman [Jodey] Arrington [R-Texas] till late last night," Johnson said. "We were working out the details of that. I'm expected to be [notified] today for a markup on Thursday. And you will see the details of that, and I'm not going to unveil it here at a press conference this morning because we're working through with members, as you know how this is done, to build consensus so we can lay that out. So, stay tuned for more on reconciliation."

The bill is expected to combine additional Pentagon funding with a grant program to encourage states to adopt voter ID and other election reforms in the SAVE America Act, and measures to address fraud in federal programs.

The White House's separate request for an $87 billion defense supplemental includes $67 billion for the Iran conflict, funds to curtail the ongoing Ebola outbreak, and aid for farmers, according to The Hill.

The Hill reported the proposal contains $1.7 billion for Pentagon readiness, $17.3 billion for operational costs, $1.5 billion for fuel costs, and $1.2 billion for administration priorities. It also includes $21 billion for munitions, $5.1 billion for cybersecurity and autonomy, $2.4 billion for drones, $800 million for National Guard backing, and $12.1 billion for other departments' classified programs.
