Senate Republicans say they have the votes to pass a package of $9 billion in spending cuts, which would give President Trump another big legislative victory in less than a month after GOP leaders quelled a revolt from members of the powerful Appropriations Committee.

Russell Vought, the director of the Office of Management and Budget (OMB), told reporters Tuesday that the so-called rescissions package now has enough votes to pass the Senate after he and the Senate GOP leaders agreed to an amendment to remove cuts to the President’s Emergency Plan for AIDS Relief (PEPFAR), the global initiative launched by President George W. Bush in 2003 to combat AIDS.

Vought, the administration’s chief budget watchdog, also worked out a side deal with Sen. Mike Rounds (R-S.D.) to redirect money in the Interior Department to help approximately 28 radio stations across 14 states that broadcast onto tribal lands who are at risk of being hurt by $1.1 billion in cuts to the Corporation for Public Broadcasting.

As a result of the last-minute dealmaking, the overall size of the rescissions package is expected to shrink slightly from $9.4 billion to $9 billion.

Getting Rounds to agree to vote for the package is a big win for the White House and Senate Republican leaders, as they can only afford to lose three GOP votes and still pass the package.

Senate Appropriations Committee Chair Susan Collins (R-Maine) and Sen. Lisa Murkowski (R-Alaska), a senior member of the Appropriations Committee, had expressed misgivings over supporting the bill before it came to the Senate floor.

Collins announced early last month that she did not support rescissions to PEPFAR and global health programs while Murkowski said she had problems with the cuts to public broadcasting.

Senate Republicans control a 53-to-47-seat majority and can rely on Vice President Vance to break a tie vote.

Senate Majority Leader John Thune (R-S.D.) hailed the bill as a key piece of Trump’s legislative agenda and an important “down payment” on reducing the size of the federal government.

“What we’re talking about here is one-tenth of 1 percent of all federal spending,” he told reporters after Senate Republicans met with Vought on Tuesday, promising that Senate GOP colleagues would have a chance to offer amendments to the package.

“This is something that all of us believe is a priority. When you have $36 trillion dollar debt, we have to do something to get spending under control,” he said. “We can start to get this thing back into balance.”

He also highlighted the tax cuts and cuts to federal Medicaid and food assistance spending as part of the broader Republican strategy to spur economic growth and “spending restraint” in the federal government.

Senate GOP leaders and Vought agreed Tuesday to a substitute amendment to the bill that would not include PEPFAR cuts.

“We’re fine with it,” Vought told reporters after meeting with GOP senators.

Thune later explained “there was a lot of interest among our members in doing something on the PEPFAR issue.”

He described the change as “small” and expressed hope that House conservatives could accept it when the measure returns to the lower chamber for final approval later this week.

Republican senators pressed Vought during the private lunch meeting Tuesday to provide more details about how Trump’s OMB would make cuts to federal programs covered by the $9 billion rescissions package.

Republican members of the Senate Appropriations Committee aren’t happy over what they view as the White House budget office’s reluctance to respond promptly and in full detail to their requests for information.

“We’d like to see the appropriations process be the place that determines what we spend and what we don’t spend,” said a Republican senator who requested anonymity to express concern about supporting the rescissions package.

The lawmaker said “appropriators are accustomed to having line-by-line numbers that reflect an account,” and the administration isn’t providing that level of detail.

The source said there are about a dozen Republicans who have concerns about the White House driving the rescissions process, but most of them will vote for the package because they’re under heavy pressure from Trump and their leaders to support it.

Trump last week threatened to withhold his endorsements from Republican senators who vote against his plan to claw back funding previously appropriated by Congress.

He warned that “any Republican that votes to allow” PBS and NPR to “continue broadcasting will not have my support or Endorsement.”

Even so, Republican senators are not thrilled about letting Trump dictate spending decisions to them from the White House.

During her opening statement at the Senate Appropriations Committee’s hearing on the rescissions package last month, Collins said that passing stand-alone rescissions packages is not the “primary way for Congress to effectuate rescissions” and that her panel “regularly” trims programs in its annual spending bills.

She said the president’s rescissions request left out key details, such as whether a $500 million cut to the Global Health Programs account would affect “lifesaving programs like Gavi, the Vaccine Alliance.”
