NBC learned about employee screening due to data leaks on migration operations in the United States

The U.S. Department of Homeland Security (DHS) has begun lie detector testing employees to identify those responsible for leaking information to the media about migration operations. This was reported on March 8 by NBC News.

Border Commissioner Tom Homan and Homeland Security Secretary Kristy Noem attributed the lower-than-expected number of arrests to recent leaks of information about cities where police planned to conduct operations.

According to sources familiar with the current use of polygraphs, so-called lie detectors are now being used to ask employees across the agency specific questions about leaked classified documents or confidential information.

"We have identified two individuals leaking information here at the Department of Homeland Security, who told people about our operations and endangered the lives of law enforcement officers," Noem said in a video message posted on the X network.
