Homeland Security Secretary Kristi Noem said that as the number of people trying to illegally enter the United States is at a historically low level, she is now focusing on those who are already in the country.

President Donald Trump took office promising to clamp down on immigration, and now, fewer migrants are reported at the border, as recently witnessed by the Washington Examiner. Noem appeared Monday on Fox News’s Jesse Watters Primetime to unveil a new advertisement directed toward the illegal immigrants who remain in the country.

“It has been incredible to see the numbers trickle down almost to zero, you know, we are talking less than a couple hundred people that we are encountering a day when it was literally over 10, 11,000 under Joe Biden,” Noem said. “So it has been remarkable just what President Trump has been able to accomplish in these first few weeks of his administration.”

The secretary lamented that Trump still does not have his full Cabinet in place. Noem was among the first confirmed by the Republican-controlled Senate. She continues to face opposition from Democratic mayors and governors who are clinging to their respective sanctuary statuses, but she said federal statutes on immigration are “more powerful than some of the laws that these cowards are standing behind.”

“That is why I’m excited to get Pam Bondi and the Department of Justice on board and use every authority that we have and work together on a plan to make sure that we are prosecuting everybody to the fullest extent of the law that we can,” Noem said.
