WASHINGTON — President-elect Donald Trump said Tuesday night he will nominate South Dakota Republican Gov. Kristi Noem to lead the U.S. Department of Homeland Security, which will carry out Trump’s plan to conduct mass deportations of millions of people in the country without proper legal status.

“Kristi has been very strong on Border Security,” Trump said in a statement.  “She will work closely with “Border Czar” Tom Homan to secure the Border, and will guarantee that our American Homeland is secure from our adversaries. I have known Kristi for years, and have worked with her on a wide variety of projects – She will be a great part of our mission to Make America Safe Again.”

DHS is the agency primarily responsible for immigration enforcement and border security and handles temporary protections to allow immigrants to live and work in the United States. As Trump rolls out his nominees, Noem would be the first governor to get the nod for the Cabinet.

DHS has about 260,000 federal employees and a nearly $62 billion discretionary budget authority.

The news had already caused a backlash among Democrats even before Trump’s announcement, as media reports said Noem would be selected.

“With a long history of championing Trump’s draconian immigration policies, Governor Kristi Noem will carry out his cruel plans without a second thought,” Massachusetts Sen. Elizabeth Warren said in a statement.

Noem said in a statement she is “honored and humbled” to be selected.

“I look forward to working with Border Czar Tom Homan to make America SAFE again,” said Noem. “With Donald Trump, we will secure the Border, and restore safety to American communities so that families will again have the opportunity to pursue The American Dream.”

Noem, a staunch Trump ally, was one of several Republican governors who sent U.S. National Guard troops to the southern border in Texas, in a rebuke to the Biden administration and its immigration policies. She’s also visited the southern border several times.

Noem served in Congress from 2011 until 2019, when she left after winning her 2018 run for governor. She’s in her second term that is set to expire in 2026.

While in Congress, she served on the U.S. House Armed Services, Ways and Means and Agriculture committees.

Noem did not sit on the committee that provides oversight for DHS, the Homeland Security Committee.

Noem joins border czar

In Trump’s second administration, Noem would join several former Trump officials who were the architects and biggest defenders of his hard-line immigration policies. The three are among Trump’s first staffing announcements.

On Monday, Trump dubbed the former acting director of Immigration and Customs Enforcement in the previous Trump administration, Homan, as his “border czar.” Homan backed the controversial “zero tolerance” policy that separated nearly 5,000 migrant families at the southern border.

Stephen Miller, who steered many of Trump’s first-term immigration policies, is set to join the White House as a deputy chief of staff for policy.

Vanessa Cárdenas, the executive director of the immigration advocacy group America’s Voice, said in a statement that the appointment of Miller and Homan signals that “mass deportations will be indiscriminate and unsparing.”

“The Stephen Miller and Tom Homan appointments are disturbing, if unsurprising, signals that we should take Donald Trump seriously and literally about his proposed largest deportation operation in American history and the unsparing, indiscriminate, and costly nature of what’s to come,” Cárdenas said.

Noem’s nomination to Trump’s Cabinet would have to go through Senate confirmation, where she could face questions about an anecdote in her memoir. She retracted a story about meeting North Korean dictator Kim Jong Un after reporters questioned whether the meeting actually happened.

Additionally, in the same memoir, she disclosed that she shot her 14-month-old puppy, named Cricket, because of behavioral issues. The revelation drew intense criticism from both sides of the political aisle.

Vast responsibilities

DHS is a sprawling agency consisting of  U.S. Customs and Border Protection, Immigration and Customs Enforcement, the Federal Emergency Management Agency, Transportation Security Administration, U.S. Secret Service and U.S. Coast Guard, among other national security agencies.

The Secret Service is under intense scrutiny after major shortfalls in its prevention of the first assassination attempt against Trump last summer, where he sustained an injury to his ear. That first assassination attempt in Butler, Pennsylvania, led to the director, Kimberly Cheatle, resigning.

Ronald L. Rowe, the U.S. Secret Service deputy director, is currently serving as the acting director, and was praised for the agency’s swift action in the second assassination attempt against Trump at his private golf course in Florida.
