Rep. Steve King (R-Iowa) is calling for comprehensive immigration reform to be put on hold in light of Monday's bombing at the Boston Marathon, citing speculation (since deemed misplaced) that the attacker was a student from Saudi Arabia.

"Some of the speculation that has come out is that yes, it was a foreign national and, speculating here, that it was potentially a person on a student visa,” King told National Review. “If that’s the case, then we need to take a look at the big picture.”
