A group of rebel Republican lawmakers is holding up all bills on the floor of the US House of Representatives.

The reason for the blockage is the group's frustration with the reluctance of their Senate colleagues to pass an election integrity bill, the Save America Act.

President Donald Trump, who has called the Save America Act his top legislative priority on numerous occasions, also called for GOP rebels in the House to stop 'grandstanding' last week, and not cede legislative power to Democrats. 

Still on Tuesday, 14 Republicans joined Democrats and voted against a 'rule' that would have lifted a pause on all legislative business on the floor of the US House.

Legislative priorities held up in the crossfire include the National Defense Authorization Act (NDAA), as well as the annual package of spending bills, including one to fund the State Department.

House lawmakers are running out of time to get the bills passed before the July 4th recess break next week. Their Senate colleagues have already left for their two-week break.

House Republican Speaker Mike Johnson is doing his best to steer his conference forward, telling members of the media on Tuesday that he was working to resolve the inner clashes among his colleagues and still get bills passed.

Representative Anna Paulina Luna has been a key voice in the fight to pass the SAVE America Act, and clashed earlier on Tuesday with Congressman Tom Cole, the chairman of the powerful Appropriations Committee in the House.

Luna called Cole 'messy' in an X post after he told Politico, 'if she wants to be a senator, she should run for the Senate,' before adding, 'Trying to use the House in that way just makes us ineffective — as ineffective as they are.'

Representative Lauren Boebert was another House member who voted to keep the impasse going, noting, 'I was gonna behave and be a good girl and vote for it, but it was going down anyway. May as well play.'

Jim McGovern, the most senior Democrat on the House Rules committee, spoke out about the GOP chaos during a House floor speech on Tuesday. 

'What on earth are we doing here?' he said, adding, 'Every week, wondering if someone's going to throw a fit, if Donald Trump is going to post something crazy and blow everything up, if Mike Johnson is going to bring something to the floor when he doesn't have the votes.'

Trump threatened to imperil House Speaker Mike Johnson's legislative agenda last week when he refused to sign a landmark housing bill unless the SAVE Act was passed.

But the pair met last Thursday and presented a united front, with the President later posting a Truth Social urging hardline GOP lawmakers to end the 'grandstanding,' and appearing to concede that the SAVE Act should not derail other Republican priorities.

Asked about Trump's wishes to avoid obstructionism on the floor of the House, Luna told the Daily Mail on Sunday, 'We don't call it obstruction, we call it how the sausage is made, and as you know, DC legislation is a messy thing, but we always get it done.'

Luna said that an amendment delivering the SAVE Act in full would be attached to the NDAA 'as just a vehicle to actually get it passed.'

The House has passed the SAVE America Act three times, but it cannot clear the 60-vote filibuster threshold in the US Senate. Even if all 53 Republicans were to vote for the bill, they would not be able to peel off the support of seven Democrats.
