Lawmakers haggling over border dollars much lower than Trump's demand

Lawmakers seeking a deal on border security that would avert a second partial government shutdown are haggling over figures below President TrumpDonald John TrumpAmash responds to 'Send her back' chants at Trump rally: 'This is how history's worst episodes begin' McConnell: Trump 'on to something' with attacks on Dem congresswomen Trump blasts 'corrupt' Puerto Rico's leaders amid political crisis MORE's demand for $5.7 billion in funding for a wall on the Mexican border.

Republican negotiators are pushing for $2 billion or more in funding, while Democrats say they hope the figure will not go above $1.6 billion.

Just as important are specifications for how funds can be spent, with Democrats pushing for specific restrictions on what kinds of barriers could be built and where.

A bipartisan Senate bill last year included $1.6 billion in funding.

Lawmakers face a Feb. 15 deadline to reach a deal and are working through the weekend to try to get one in place by Monday, which would give the House and Senate enough time to pass a bill before funds for parts of the government would run out.

Trump has largely allowed talks to proceed unimpeded, but negotiators are concerned that he will dismiss the final result as insufficient.

At that point, they worry, he could allow the government to shut down for the second time this year, or declare a national emergency to circumvent Congress and build the wall using other funds.

“The details I’m hearing about are not things the president should sign,” he said.

Other subjects under discussion include funding for detention beds for Immigration and Customs Enforcement. Democrats are seeking to limit the number of beds as a step toward phasing out family detentions.

The sides are also debating how much funding to provide for Puerto Rico as part of a disaster relief bill included in the measure.

The final spending number may not be as important as the details over how the funds can be spent, Meadows said.

"If the final proposal is too restrictive, I would be more inclined to encourage him to do a clean CR and do the national emergency, but again, it’s the details," Meadows said of Trump, referring to a continuing resolution that would simply extend 2018 funding levels through the end of the year.
