President Obama on Tuesday will lead a special summit on the need to take in Syrian refugees, just days after weekend terrorist attacks that are raising more questions about whether the U.S. should be cracking down on immigration instead of opening the doors further.

Plans for Obama to lead the summit were months in the making, long before Ahmad Khan Rahami allegedly planted a pressure cooker bomb in New York that detonated, injuring 29 people. Rahami, a naturalized U.S. citizen born in Afghanistan, is also thought to be responsible for bombs discovered in New Jersey.
