Noem's government shutdown video not airing at SAN

• That law aims to ensure federal programs are administered in a nonpartisan fashion.

Worth noting: Airports do regularly display videos from the Department of Homeland Security (DHS) secretary, though those typically focus on safety or travel procedures, not partisan messaging, the Washington Post reports.

Catch up quick: Noem's video says the TSA aims to ensure efficient, pleasant and safe travel — but "Democrats in Congress refuse to fund the federal government."

• "Because of this, many of our operations are impacted, and most of our TSA employees are working without pay," Noem continues.

What they're saying: "Our focus remains on ensuring safe, efficient airport operations and providing timely, relevant information to travelers," airport spokesperson Nicole Hall said in an email to Axios. "Our messaging continues to focus on making the customer experience as easy and efficient as possible."

Zoom out: Several major airports confirmed to Axios that they won't show the video, including across California and in Philadelphia, Atlanta, Seattle, Portland, Phoenix, Charlotte, Las Vegas and Miami.

The bottom line: Staffing shortages have plagued many airports during the shutdown.

• Under a lapse in appropriations, thousands of TSA workers and air traffic controllers must work without pay, per agency shutdown procedures.
