Alabama Sen. Jeff Sessions said late Thursday that President Obama’s refusal to specifically connect recent terrorism acts to radical Islamic groups will impede the world’s ability to fully address the threat.

“I think it is a legitimate concern that the president is not seemingly taking this seriously enough,” Sessions told Fox News’ Greta Van Susteren. “This whole idea — refusal — to address the reality of the threat we face does impact our ability to defend America and help the whole world see the nature of the threat we face which is very real.”
