Raid on ISIS Leader 'Picture Perfect,' Sen. Dianne Feinstein Says

It's "the kind of one-two punch that we should do more of," she says.

"I believe that if we're not going to put troops on the ground, then we've got to use our Special Operations Forces to go in and collect intelligence; also be able to capture people that might be able to be helpful," she said Sunday on "This Week."

On the continuing strength of ISIS, Feinstein called the group "organized" and "an impressive fighting force."

"It occupies territory. It runs a government. And most importantly it is evil. It annihilates in the most brutal of ways," Feinstein said. "And so I think that we have to get very serious about what we're going to do not only to contain but to eradicate this force."
