How Homeland Security could change under Markwayne Mullin

Sen. Markwayne Mullin of Oklahoma appeared before the Senate for his confirmation hearing Wednesday as Trump's nominee for Homeland Security secretary. Mullin, a Republican businessman and senator, would oversee the department responsible for border security, immigration enforcement, and disaster response if confirmed. His nomination reflects the Trump administration's focus on hardline immigration and border control policies. The hearing is a critical step in the confirmation process, requiring Senate approval before he can assume the position. Mullin's background in business and his positions on immigration enforcement will likely shape how the department operates over the next two years.
