On Tuesday, Fox News’ Bill Hemmer grilled White House press secretary Jen Psaki on the White House recently ending its mask mandate just in time for President Biden’s State of the Union address. 

Washington, D.C., the White House, and the U.S. Capitol all ended their mask mandates in the run up to Biden’s address.

The exchange took place during an interview on Hemmer’s program “America’s Newsroom.”

Hemmer to Psaki: ‘What changed in the science yesterday, Monday, as opposed to a week ago Monday?’

Hemmer noted to Psaki that Washington, D.C., ended mask mandates early Tuesday morning and the White House has also stopped mandating masks.

Hemmer asked the press secretary, “Jen, there are no masks in Washington, D.C. as of midnight last night. What changed in the science yesterday, Monday, as opposed to a week ago Monday?”

Psaki replied, “It wasn’t actually yesterday, Bill. What the CDC did is they put out guidance last Friday that identified recommendations depending on what the hospitalization rates are in your part of the country.”

“We’re currently in a part of the country in Washington, D.C., where it’s very low, the rates,” she continued. “So we’re not, the recommendation is not to wear masks. We aren’t wearing masks at the White House, the President’s not going to wear a mask tonight.”

The CDC Changed Its Guidelines On Friday

“I committed that I would follow the science,” Biden told NBC News, adding that the rollback of mask mandates in states and cities across the country was likely  “premature.”

“And the science as put forward by the CDC and the federal people and I think it’s probably premature but it’s a tough call,” the president said.

As of Friday, the CDC updated its guidelines that now show that mask-wearing indoors is no longer recommended for the public at large.
