House Speaker Nancy Pelosi (D-Calif.) faced a defeat of her agenda, but it wasn't at the hands of Republicans in the House of Representatives, but rather the progressive members of her own party.

Democrats were scheduled to vote to defeat a request from President Donald Trump to raise spending for the Department of Defense on Wednesday, but that vote has been canceled.

Progressive Democrats refused to join centrists to pass the rebuke against the president, according to the Washington Times.

Ranking Budget Committee Republican Rep. Steve Womack of Arkansas mocked the Democrats for their failure.

"House Democrats had to throw in the towel on a bill that addresses only a small part of the budget," Womack said. "The result is another embarrassing failure to govern."

Progressive Democrats wanted an amendment to increase spending by $67 billion over two years, and they threatened to defeat the leadership budget bill without the amendment.

"Progressives will continue to seek equality in outlays between excessive Pentagon spending and critical domestic priorities and end decades of harmful austerity imposed on our communities," said Congressional Progressive Caucus co-chair Rep. Pramila Jayapal (D-Wash.).

"This is not an outcome," said Pelosi of her defeat. "This is a process."

Pelosi also notably ridiculed one of the leaders of the progressive faction, Rep. Alexandria Ocasio-Cortez (D-N.Y.) when asked how she was going to keep the Democratic Party from fracturing.

"While there are people who have a large number of Twitter followers," Pelosi said dismissively, "what's important is that we have large numbers of votes on the floor of the House."

Those votes failed to coalesce for the leadership budget effort.
