Homan has long argued tipping off Immigration and Custom's Enforcement operations potentially endangers federal law enforcement because those criminal illegals – some of which could be a part of the Tren de Aragua Venezuelan gang – could arm up against operations.
"We have identified two leakers of information here at the Department of Homeland Security who have been telling individuals about our operations and putting law enforcement lives in jeopardy," Noem said in a video posted Friday to X. "We plan to prosecute these two individuals and hold them accountable for what they've done."
NBC's sources did not know if the lie detector is how the leakers were caught, but there have been employees given the polygraph tests in multiple agencies within DHS, according to the report.
