President Donald Trump's nominee for the position of Homeland Security Secretary, Markwayne Mullin, is on the verge of Senate confirmation after a key Senate panel cleared an important procedural hurdle. The Senate Committee on Homeland Security and Governmental Affairs moved Mullin's nomination out of committee on March 19, setting up a full Senate vote likely in the coming week. The move follows questions about a mysterious foreign trip Mullin made while serving as a member of the House of Representatives, which he has previously described as a secret mission. Despite criticism from both sides of the aisle, Mullin has been supported by some within his own party, including Sen. Rand Paul, chairman of the Senate committee that advanced his nomination, who is not supporting his nomination.
