Homeland Security Secretary Markwayne Mullin told a House panel that he has canceled most contracts signed by his predecessor Kristi Noem and is reviewing others for potential conflicts of interest.

During questioning from Rep. Bennie Thompson (D-Miss.), the ranking Democrat on the committee, Mullin said he is examining contracts that may have had ties to Noem's allies. He promised to provide Congress with a complete list of contracts that have been terminated.

The review comes as part of standard transition procedures when new leadership takes over federal agencies. Mullin did not specify the nature or value of the contracts under review, but indicated that most had already been canceled.

Separately, Mullin provided Congress with updated timelines for border wall construction projects. He told lawmakers that the primary border wall stretching from the Pacific Ocean to the Gulf of Mexico is on track for completion by June 2027.

The secondary border wall system is expected to be finished by summer 2028, according to Mullin's testimony. The construction timeline represents ongoing efforts to secure the southern border that have spanned multiple administrations.

Mullin's appearance before the House panel marked one of his first major congressional hearings since taking over the Department of Homeland Security.
