Noem makes aggressive new move to ramp up arrests, deportations of illegal immigrants

Noem signed an order that deputized up to 600 special agents in the State Department's Diplomatic Security Service to help with the arrest and deportation of illegal immigrants.

"Under President Trump, the Department of Homeland Security will use every tool and resource available to secure our border and get criminal illegal aliens out of our country," Noem said in a statement. "The safety of American citizens comes first."

The move is the latest effort by the department to expand the number of officials involved in immigration enforcement, amid a push by the Trump administration to aggressively increase the arrests and deportation of illegal immigrants.

DHS has deputized IRS employees, law enforcement components of the Justice Department and law enforcement officials with the Texas Attorney General's Office.

"It is DHS's understanding that the Department of Treasury has qualified law enforcement personnel available to assist with immigration enforcement, especially in light of recent increases to the Internal Revenue Service's work force and budget," Noem said last week.

Meanwhile, the administration has secured additional cooperation at the border from Mexico and Canada, as well as agreements from Venezuela and Colombia to take back their nationals.
