WASHINGTON (AP) — Homeland Security Secretary Jeh Johnson is defending President Barack Obama's executive actions on immigration, while GOP lawmakers are struggling to find the best way to stop them.

Johnson is appearing Tuesday before the House Homeland Security Committee. It's the Obama administration's first testimony on the issue since the president announced plans two weeks ago to shield some 4 million immigrants here illegally from deportation.

In written testimony Johnson calls the moves "simple common sense."

But Republicans have vowed to stop Obama, and as they returned to Capitol Hill from a Thanksgiving break they were meeting to decide how.

Conservatives circulated draft legislation that would block any money from being used to fund Obama's actions. Others warned that including this in must-pass spending measures would court a government shutdown.
