She said that “3 million illegal aliens have left the US, we have located 145,000 children, FEMA delivered disaster relief at a 100% faster rate, we ushered in the golden age of travel, saved the American taxpayer $13 billion and revitalized the US Coast Guard.”

Markwayne Mullin says focus will be on Homeland Security

Meanwhile, Markwayne Mullin briefly addressed his nomination while speaking to reporters at the US Capitol, signaling that his immediate focus would be on securing support for confirmation while outlining his priorities for the role.
