Rep. Mark Meadows on Wednesday raised concerns that Congress might pass a spending deal that his conservative caucus can't support.

"I'm afraid that the numbers will get so high and the debt ceiling will get added and it will be a Christmas tree of spending, that a lot of votes will be bought," the North Carolina Republican, who is the chairman of the House Freedom Caucus, said on MSNBC's "Morning Joe."

"So, it'll be quote a bipartisan deal, but you'll end up with 120 or 140 Democrats and maybe about the same on Republicans, sending this to the president's desk."

Although the House recently passed a short-term spending agreement, a longterm deal has yet to be announced.

Legislators have signaled that Congress is close to finalizing a two-year spending agreement, which could raise the debt ceiling and provide increased funding for the military, but Meadows said his group has been weakened after backing the short-term bill in the House.

"We had to make a decision last night," he said. "We had an emergency meeting of the Freedom Caucus, really the plan that we had was to go ahead and fund defense and keep the line straight on non-defense."

"We knew by giving that vote that potentially we would use all our leverage over the next 48 hours," Meadows added.

The congressman also said that Congress must address spending reform, including defense spending, despite the GOP infighting that's likely to occur.

"It is time that we make sure that the federal taxpayer's dollar is accounted for properly," he said.

"You're going to probably see a whole lot more fighting and really debating on that particular issue in the coming weeks."
