Trump's Homeland Security Pick: A "MAGA Warrior" and Ex-MMA Fighter

President Trump has chosen a controversial figure to run the Department of Homeland Security (DHS). His pick is Oklahoma Senator Markwayne Mullin. Mullin is a former mixed martial arts (MMA) fighter. He calls himself a "MAGA warrior." MAGA is the acronym for Trump's "Make America Great Again" political movement. In the Senate, Mullin strongly supported the Trump administration's immigration plans. This includes a campaign for mass deportations. The DHS would lead this effort if it becomes policy. The role of Homeland Security secretary is a key cabinet position. The department handles border security, immigration enforcement, and disaster response. Mullin's nomination must be confirmed by the U.S. Senate.
