Homeland Security Secretary Kristi Noem announced she had fired the employees in her department who were leaking information to the press.

This comes as activists against Immigration and Customs Enforcement have engaged in a variety of protests. Social media is rampant with warnings about the location of ICE officers, and Los Angeles saw flyers on display relaying the leaked names, faces, and job descriptions of other officers.

“I have found some leakers. We are continuing to get more. They will be fired. There will be consequences. Remember, when they leak information to the press in order to blow an op, they are putting law enforcement lives in jeopardy,” Noem said on Fox News’s Hannity. “They are risking their lives and putting their families in the position where they have to live without those individuals any further. So, you bet we have used every tactic that we have.”

Among the tactics, Noem said she is implementing polygraph testing to examine the testimonies from staff. Digital searches are also ongoing.

KRISTI NOEM CELEBRATES DECREASED BORDER CROSSINGS

“It’s amazing how these bureaucrats, who have an agenda to stop the work that we’re doing to bring safety to America, how they will sell each other down the river if it’s just to protect themselves,” Noem said. “So don’t worry. I am doing everything to find these leakers and get rid of them so that we can do our work and our law enforcement officers and agents can do it safely.”

Over the weekend, only 200 migrants attempted to cross the United States’s southern border. This was the lowest figure reported in a single day in 15 years. Noem credited President Donald Trump for the decrease in border crossings.
