Portland International Jetport has joined several major U.S. airports in declining to display a video from Homeland Security Secretary Kristi Noem that blames congressional Democrats for the government shutdown and related travel disruptions.

Airport authorities from Buffalo to Phoenix have determined the video contradicts various local, state or federal regulations or policies that prohibit the use of public resources for political or partisan messaging or activities.

Jetport officials received a request Friday from the Transportation Security Administration asking them to “voluntarily display” the video on monitors throughout the terminal at Maine’s largest airport, according to a statement emailed Tuesday to the Press Herald.

“The jetport monitors are used for safety, efficiency and security enhancements,” the statement said. “As the political nature of this video did not serve any of these functions, the jetport declined the request to voluntarily display the video on its monitors.”

TSA regulations define how and when airports may be required to display signs, the statement said.

“This video display request did not follow those requirements,” the statement said. “(The video) was political in nature and did not address any operational guidance for customers, such as limits on liquids, leaving your electronics in your bag or having a Real ID.”

At the jetport Tuesday, one of three monitors in the TSA passenger screening area was showing a video of Noem talking about the Real ID; the two other monitors were dark. Other monitors throughout the terminal were tuned to news channels, animated children’s shows and departure and arrival schedules.

Airports serving Buffalo, New York; Charlotte, North Carolina; Cleveland; Los Angeles; Phoenix; Seattle; and Portland, Oregon, also have declined to display the video because they determined that it violates local, state or federal regulations or policies, the Washington Post reported.

In the video, Noem blames Democrats specifically for the shutdown that started two weeks ago on Oct. 1.

“It is TSA’s top priority to make sure that you have the most pleasant and efficient airport experience as possible,” she says. “However, Democrats in Congress refuse to fund the federal government, and because of this, many of our operations are impacted.”

“We will continue to do all that we can to avoid delays that will impact your travel. And our hope is that Democrats will soon recognize the importance of opening the government,” she says.

The video also isn’t running in Portland International Airport in Oregon, where state law prohibits public employees from participating in political activities during working hours, spokesperson Molly Prescott told the Post.

Prescott said the video also violates the Hatch Act of 1939, which bars federal employees from engaging in political activity while on the job and is meant to ensure that federal programs are administered in a nonpartisan fashion.

Westchester County, just north of New York City, also declined to show the video. County Executive Ken Jenkins said it was “inconsistent with the values we expect from our nation’s top public officials” and “unnecessarily alarmist” in a statement on Friday.

A notice on the jetport website says it continues to operate as normal but advises travelers to check individual flights for delays or diversions related to irregular operations at other airports.

Many TSA agents and other employees are still working but are not being paid as the government shutdown nears the end of its second week, resulting in thousands of flights being delayed or canceled each day.
