President Donald Trump praised the budget deal reached by lawmakers to lift caps on defense and domestic spending on Wednesday, casting it as critical to supporting the troops.

"The Budget Agreement today is so important for our great Military," the president tweeted. "It ends the dangerous sequester and gives [Defense] Secretary [Jim] Mattis what he needs to keep America Great. Republicans and Democrats must support our troops and support this Bill!"


Congressional leaders announced they'd come to an agreement on a two-year spending deal that is expected to raise domestic and defense spending by about $300 billion, add disaster-aid spending and lift the debt ceiling enough to get past the 2018 elections.

The deal diminished the chances of Congress passing another short-term spending bill and facing the prospects of a government shutdown once more.

Despite wielding bipartisan support from congressional leadership, the agreement came under immediate fire from fiscal conservatives, who hammered Republicans from turning their backs on lowering the deficit.

“It’s a really bad idea to blow through the budget caps," Sen. Rand Paul (R-Ky.) said. "It’s bad for the country.”

It remains unclear whether the opposition will be enough to block the agreement from passing through Congress.

Defense Secretary Jim Mattis said earlier Wednesday that a shutdown “would be very damaging to the military,” stressing the need for Congress to finalize a deal on spending.

“It just paralyzes everything that we do if we go into that," Mattis said at the White House press briefing. "The ships will stay at sea. But the bottom line is training’s delayed.”
