Nearly one-third of Border Patrol's surveillance cameras along U.S.-Mexico border not working: Memo

Nearly one-third of the cameras that are part of the U.S. Border Patrol’s main surveillance system along the 2,000-mile U.S.-Mexico border are not functioning, according to an internal agency memo from earlier this month that was obtained by NBC News on Monday.

The agency wrote in the memo that the "nationwide issue is having significant impacts" on its operations. The outage was linked to “several technical problems" and it has affected anywhere between 150 to 500 cameras.

The report cited an anonymous source from within the agency who attributed the widespread problem to "outdated equipment and outstanding repair issues."

Sen. Roger Marshall slammed Homeland Security Secretary Alejandro Mayorkas for not confirming under oath whether or not the technology at the border worked.

"In April, Sec. Mayorkas admitted under oath that he could not confirm if his technology was operational. Today, it was revealed 30% of cameras are NOT functioning at the border, leading to major impacts on CBP’s operations," the Kansas GOP senator wrote on the social media platform, X.

"The fact is, this administration hasn't known who is coming into our country for a LONG time," he added. "We have NO IDEA how many unvetted gotaways are in our country- and Border Czar Kamala Harris wants the American people to give her a promotion? No shot."
