The Trump administration is accusing a Democratic senator of lobbying the Biden administration to remove her husband from a Transportation Security Administration surveillance program after the government determined that he had flown with someone known internally as a suspected terrorist.

The Department of Homeland Security revealed Wednesday morning that Sen. Jeanne Shaheen (D-NH) contacted the TSA about her husband, William “Billy” Shaheen, being subjected to enhanced screening. The department alleges that the senator personally lobbied former TSA Administrator David Pekoske to give her husband a blanket exemption from its Silent Partner and Quiet Skies program, which is used to surveil and more carefully track certain airline passengers.

“It is clear that this program was used as a political rolodex of the Biden Administration — weaponized against its political foes and to benefit their well-heeled friends,” Homeland Security Secretary Kristi Noem said in a statement. “This program should have been about the equal application of security, instead it was corrupted to be about political targeting. The Trump Administration will restore the integrity, privacy, and equal application of the law for all Americans, including aviation screening.”

A spokesperson for Shaheen’s office confirmed in an email Wednesday that the senator had contacted the TSA over the searches but denied the DHS’s allegation that she lobbied to have him removed from the list, saying she did not know that her husband had been placed on one.

“Senator Shaheen sought to understand the nature and cause of these searches,” the Shaheen spokesperson said in a statement. “Any suggestion that the Senator’s husband was supposedly included on a Quiet Skies list is news to her and had never been raised before yesterday. Nor was she aware of any action taken following her call to remove him from such a list.”
