Senate Majority Leader Harry Reid urged President Barack Obama Tuesday to “go big” on his expected immigration executive order, while saying it’s “hard to comprehend” why Republicans are threatening a government shutdown over immigration.

“I believe that when the president decides to do his executive order, he should go big, as big as he can,” Reid said. “The fact that he wants to do something on immigration, is being forced to do something on immigration, should not stop us from doing our job, and that is funding government.”
