US President Donald Trump dismissed Homeland Security Secretary Kristi Noem.

In a post on the social media platform Truth Social, President Donald Trump confirmed that Republican Senator Markwayne Mullin (48 years old) from Oklahoma will officially take over the Senate on March 31st.

Mullin's nomination will need to be confirmed by the Senate, where the Republican Party holds a majority.

Despite being dismissed from her position as Secretary, Kristi Noem, 54, will be reassigned to a new role. President Trump said she will become a special envoy for a new security initiative in the Western Hemisphere called "Shield of the Americas," which is expected to be officially announced on March 7.

Trump continues to praise the achievements under Noem's administration, particularly on border security issues, and expects his successor, Markwayne Mullin, to be an outstanding "MAGA warrior," tirelessly working to prevent crime and drugs from entering the United States.

For his part, speaking to the press, Mullin affirmed that his focus would be on keeping the country safe, while also recognizing opportunities to build on successes and address shortcomings in plans that did not go as intended.

Meanwhile, on platform X, Ms. Noem thanked the President and proudly recalled the "historic achievements" at DHS, asserting that America has the most secure border in history with 3 million undocumented immigrants having left.

American media, citing multiple sources, reported that the underlying reason for the change in leadership stemmed from President Trump's dissatisfaction with Secretary of State Noem. Specifically, Trump was reportedly very disappointed with Noem's handling of the recent large-scale crackdown on undocumented immigrants in Minnesota.

During this operation, federal immigration agents opened fire, killing two American citizens, sparking protests and outrage among the public.

Furthermore, the White House's anger was further fueled by Ms. Noem's testimony before the Senate this week. There, she revealed that the President personally approved the DHS's $220 million advertising campaign, a campaign in which Ms. Noem's image was prominently featured.

Senator Noem's departure was immediately met with approval from many senators. Senate Minority Leader Chuck Schumer bluntly called it a "welcome" departure. Senator Dick Durbin strongly criticized Noem's campaign of mass deportations as dangerous and illegal, resulting in the deaths of innocent American citizens.

Senator Adam Schiff also emphasized that the $220 million spent on Noem's personal image promotion campaign was a waste of public funds and that her dismissal should have happened long ago.

Not only Democrats, but Ms. Noem also faced public criticism from members of her own Republican party. Senator Thom Tillis called her leadership at DHS a "disaster."

Meanwhile, Senator John Kennedy, a loyal supporter of Trump, sharply questioned the effectiveness of the $220 million television advertising budget, arguing that it only served to polish Noem's personal image.

Ms. Noem is the first Cabinet member to be fired by Mr. Trump since taking office, not counting the dismissal of former National Security Advisor Mike Waltz last year for sharing sensitive information. This decision comes at a sensitive time when the DHS is partially shut down.

Currently, Democrats are firmly opposing any new funding for the agency until the Immigration and Customs Enforcement (ICE) comprehensively changes its operating methods, including limiting patrols, banning agents from wearing masks, and requiring a court order before searching private property.
