BOSTON (CBS) — A Democratic congressman from Massachusetts, who served in the Marines during the Iraq War, is among those questioning the president’s strategy concerning ISIS.

Rep. Seth Moulton, D-Salem, said he believes the Obama administration underestimated ISIS, and says the U.S. should be doing more to battle the terror group.

“Certainly calling them a JV team is an underestimation,” Moulton said. “But the point is, going forward, we need a much more comprehensive strategy.”

Moulton said the fight against ISIS cannot be waged only through military action.

“We have to defeat ISIS on social media where they are recruiting people, even fellow Americans,” he said.

The representative says ISIS is a national security threat, and calls for a serious diplomatic strategy.

“We need to have a plan to ensure political stability in places like Iraq, where ISIS was able to grow because of the political vacuum we left in the wake of our departure,” he said.
