Budget Director Mick Mulvaney blasted Democrats on Tuesday for misrepresenting a spending deal that will keep the government open until September, arguing Republicans had denied Democrats their overall goal of forcing a shutdown for political reasons

"They were desperate to show that [Republicans] were not reasonable," Mulvaney said Tuesday morning on a conference call with reporters. "They wanted a shut down."

Mulvaney pointed to the $21 billion in increased funding for the Pentagon and $1.52 billion in additional border security funds as evidence that Republicans — contrary to Democrats' claims — had not walked away from the deal with nothing.

"What happened is the American people won, and the president negotiated that victory for them," Mulvaney said.

He accused Democrats of attempting to obscure the details of the spending bill for political reasons.

"They know the truth of what's in the bill," Mulvaney said. "They know the deal the president cut, and I'm sure some of them are scared to death of what's in this bill."

The Office of Management and Budget director noted that GOP lawmakers had not given up on their push to defund Planned Parenthood, despite the fact that the spending legislation includes funding for the abortion provider.

"We have a complete defunding of Planned Parenthood as part of the healthcare bill," Mulvaney said. "Let there be no mistake about this administration's commitment to the pro-life movement."

Mulvaney also noted that the bill did not prevent President Trump from withholding cost-sharing reduction payments from insurance providers at some point in the future. Those payments are necessary to keep insurance providers from fleeing the Obamacare markets, but have proven controversial in the past because the Obama administration decided to provide the payments without consulting Congress.

"Nothing in this bill obligates us to make any Obamacare CSR payments at any point in this process," Mulvaney said. "We are not making any commitments in this bill."

Republican critics of the spending deal have questioned why the administration seemingly conceded so many of its priorities — including appropriations specifically for the border wall — in order to strike a deal seen as slanted toward Democrats.
