Sarah Huckabee Sanders pinch hit for Sean Spicer at today's White House briefing, answering questions about the ObamaCare replacement bill that passed in the House yesterday.

Sanders said that Spicer, the White House Press Secretary, was out today on Naval Reserve duty. 

Sanders, who is the daughter of former Arkansas Gov. Mike Huckabee, is Spicer's top deputy.

Dana Perino was the last woman to serve as press secretary, doing so under President George W. Bush. 

Sanders first announced that President Trump had just signed a $1.1 trillion spending bill that averts a government shutdown. 

Sanders said the White House "expects changes" to be made to the American Health Care Act in the Senate. 

She was also asked about criticism of the House for passing the bill without a score from the Congressional Budget Office.

"I know the gospel pretty well. The CBO is not the gospel. They've been wrong before, they could certainly be wrong again," she said.

She also took issue with a reporter who cited a new Politico report that the administration would "gut" the Office of National Drug Control Policy.

"Never use Politico for a source for your story," she said, emphasizing that the opioid crisis is a "huge priority" for the president.

The report cited critics who argued that cutting funding for the office would hurt efforts to combat the opioid epidemic. 

Sanders responded to reports about the firing of White House chief usher Angella Reid, the first woman to hold the position. 

"We left on very good terms and wish her the very best," said Sanders, adding that a "transition" of staffers is not uncommon after a new administration comes in.
