The bill would cost $659 million through the final two months of this fiscal year, far less than the $3.7 billion requested by President Barack Obama for this year and next, and a sharp reduction from the $1.5 billion initially proposed by the House spending committee. The cuts were designed to win over skeptical conservatives and give lawmakers something they could pass before leaving Washington at week's end for their annual August recess.
The measure also includes policy changes rejected by most Democrats that would allow unaccompanied youths who've been arriving by the tens of thousands from Central America to be turned around quickly at the border and sent back home.
"I think there's sufficient support in the House to move this bill," House Speaker John Boehner told reporters after meeting with rank-and-file lawmakers on the issue, though he said there was more work to do.
A vote was set for Thursday.
Even if it does pass the House, the bill is certain to be rejected by the Democratic-run Senate, which was set to take a procedural vote on its own $2.7 billion border package Wednesday.
The Senate bill, which does not include the policy changes embraced by the House, lacks GOP support and seemed unlikely to move forward. The Senate bill also includes money for Western wildfires and Israeli defence that was left out of the House version. So there appeared to be no path to a compromise that could send a bill to Obama's desk ahead of the five-week congressional recess.
Complicating matters further, Senate Majority Leader Harry Reid floated the idea of using the House measure as a vehicle for advancing a comprehensive immigration reform bill including a path to citizenship for millions now here illegally. That legislation passed the Senate a year ago but stalled in the House. "Maybe it's an opening for us to have a conference on our comprehensive immigration reform," Reid told reporters.
House conservatives have warned repeatedly that anything they pass could become a vehicle for the Senate's immigration bill, and Reid's comments seemed to confirm their worst fears. Perhaps that was intentional, since the result could be to limit conservative support for the border spending bill in the House.
Boehner responded angrily, accusing Reid of "making a deceitful and cynical attempt to derail the House's common-sense solution."
"So let me be as clear as I can be with Senator Reid: the House of Representatives will not take up the Senate immigration reform bill or accept it back from the Senate in any fashion," Boehner said in a statement.
If Reid's ploy was intended to upset Boehner's efforts, it was unclear that it would succeed.
Numerous House Republicans have said that they did not want to go back to their districts to face voters without acting to deal with the influx of kids and teens showing up at the South Texas border without their parents, mostly from El Salvador, Honduras and Guatemala. More than 57,000 have arrived since October, many fleeing vicious gangs and trying to reunite with family members, but also drawn by rumours that once here, they would be allowed to stay.
Ahead of Reid's remarks, GOP lawmakers said that their measure appeared to enjoy widespread support, although some conservatives said they remained opposed.
"Frankly, we need to show that we can act and act thoughtfully, responsibly and quickly," said Rep. Tom Cole, R-Okla., who supports the measure.
But Democrats rejected the legislation, largely because of the legal change to a 2008 trafficking law that guarantees immigration hearings for unaccompanied kids who arrive here from anywhere other than Mexico or Canada. The House GOP bill would allow the Central American kids to be treated like Mexican kids, who can be turned around quickly at the border unless they can convince Border Patrol agents that they have a credible fear of return meriting additional screening.
"If they try to change the law that covers and protects the rights of these refugee children, we are going to oppose it," said Rep. Nydia Velazquez, D-N.Y. "We will vote against it and they will not have the votes to pass it."
The House GOP legislation includes $405 million for the Homeland Security Department, which administration officials have said is in danger of running out of money for customs and border activities in coming months. It includes $22 million to hire more temporary immigration judges and outfit immigration courtrooms with video teleconferencing equipment, and $35 million to double spending for the National Guard presence on the border. In addition, $197 million would go to the Health and Human Services Department for housing and humanitarian assistance for the minors, and $40 million for Central American governments to help with repatriation efforts.
