Democrats have attacked the leadership of Homeland Security Secretary Markwayne Mullin during his first Senate hearing since being tapped by President Donald Trump. Democrats called his threats to pull officers from airports in sanctuary cities “insane” and are accusing his department of reckless spending. Mullin, a former Oklahoma senator, defended himself, calling the attacks “outlandish.” The Senate is considering legislation to fund immigration enforcement agencies through the end of President Trump’s term, bypassing Democratic support. Mullin’s threats to withdraw officers could disrupt international travel, especially with the upcoming World Cup.
