WASHINGTON >> Congressional negotiators today inched toward a potential agreement on a catchall spending bill that would deny President Donald Trump’s request for immediate funding to construct a wall along the Mexico border. The emerging measure would increase the defense budget and eliminate the threat of a government shutdown on Trump’s 100th day in office this Saturday.

Top Senate Democrat Chuck Schumer said Republican negotiators were following the lead of Trump, who signaled Monday evening that he would not insist on $1 billion worth of wall funding now as an addition to the $1 trillion-plus spending bill. Trump told a gathering of conservative media reporters that he might be willing to wait until September for the funding.

Other stumbling blocks remain, but the decision by Trump and his GOP allies to back down on the wall steered the talks on the spending measure in a positive direction.

Senate Majority Leader Mitch McConnell, R-Ky., said he was optimistic the talks would produce “an agreement in the next few days.”

An existing temporary funding bill expires Friday at midnight and all sides anticipated that another stopgap measure would be required to buy time for the House and Senate to process the massive spending bill, which would wrap together 11 unfinished agency spending bills through September.

Trump campaigned throughout the country last year promising a wall across the entire 2,200 mile southern border, promising that Mexico would pay for it. But while the idea is a priority of Trump’s most fervent supporters, it is resolutely opposed by Democrats and even many Republicans, who see it as wasteful and who prefer other steps like new technologies and additional border agents to curb illegal immigration.

“I support additional border security funding,” said Sen. Lindsey Graham, R-S.C., a GOP critic of Trump who dined with the president Monday at the White House. “But a 2,200-mile wall, I don’t think there’s a whole lot of support for it.”

Trump vowed to fight for the wall.

“The wall is going to get built,” he said at the White House today. Asked when, he said, “Soon.”

Democrats vowed not to give up, either, and look forward to the fight.

“It’s not a negotiation,” Schumer said. “No wall.”

Meanwhile, Trump appeared poised to procure about $15 billion to boost the military. Democrats said they were satisfied with the emerging outlines of the measure, which stick closely to versions of the legislation that were being negotiated late last year.

Sen. Patty Murray, D-Wash., observed that GOP negotiators “have simply ignored” a roster of “$18 billion in extreme cuts” offered by White House budget director Mick Mulvaney to lower the measure’s cost. The measure would also while maintain foreign aid accounts that Trump has targeted, along with a series of grant programs popular with lawmakers in both parties, such as community development block grants.

Several issues remain unresolved. Democrats, with McConnell’s help, were pushing to extend health benefits for 22,000 retired Appalachian coal miners and their families whose medical coverage is set to expire at the end of April. Democrats faced White House opposition in an uphill battle to give Puerto Rico help with its Medicaid commitment, while Republicans are pressing policy “riders” to undo new Obama-era financial regulations.

Another potential stumbling block involved a recent threat by Trump to scuttle a portion of former President Barack Obama’s health law that helps low-income people afford insurance policies.

Democratic votes are invariably needed to pass catchall spending bills, which typically are resented by many tea party Republicans. That gave Democratic leaders like Schumer and Pelosi significant leverage, and the top Democrats had earlier this month taken a hard line in response to Trump’s threats to deny the Obamacare payments for out-of-pocket costs for the poor, injecting the issue into the spending bill talks. Schumer, however, backpedaled on Tuesday and would no longer insist that the issue be addressed in the catchall bill and the White House sent conciliatory signals as well.

Meanwhile, House lawmakers returned to Washington this evening and faced a renewed push from the White House to revive their beleaguered health care bill in hopes of attracting enough votes to finally push it through the House.

Leaders of the conservative House Freedom Caucus met to consider a proposal to change the GOP legislation to let states get federal waivers to ignore coverage requirements imposed by President Barack Obama’s health care law. These include a prohibition against insurers charging higher premiums for seriously ill customers.

The plan “has real merits worthy of consideration for all the Freedom Caucus folks,” said Rep. Mark Meadows, R-N.C., leader of that group. He helped craft the idea with Rep. Tom MacArthur, R-N.J., a leader of a group of GOP moderates.

Meadows and numerous conservatives and moderates opposed an initial version of the bill, forcing House leaders to withdraw the measure before a planned vote last month. GOP leaders are trying to determine if the proposed changes can gain enough votes to pass, but that remains uncertain.
