The Department of Homeland Security is the most important agency for immigration enforcement, and critics regard McCaul as too lax in this area. He was one of just 19 House Republicans who signed on to then-Speaker John Boehner's immigration principles, which hardliners regarded as supporting amnesty for illegal immigrants.
The Texas congressman wasn't helped when he was praised by President Obama's Homeland Security Secretary Jeh Johnson. "On his behalf, I don't know anybody who is stronger on border security in Congress that I have dealt with," he told the Washington Times, a comment that is likely to be used against him in the future.
Many immigration hardliners prefer Kansas Secretary of State Kris Kobach, who has helped formulate tough state laws designed to curb illegal immigration, for the Department of Homeland Security. Trump has also interviewed Milwaukee County Sheriff David Clarke. Clarke and Kobach would likely be much harder to confirm than McCaul, who is popular on Capitol Hill.
Lol if McCaul is confirmed for the nomination, I will seriously lol...that would confirm somewhat that Trump really is doing whatever he wants and his campaign rhetoric was just a ploy to get elected
