Leading Democratic Sen. Dianne Feinstein said on Sunday the United States is not doing enough to fight Islamic State, and the group is gaining strength outside Iraq and Syria.
Feinstein, the ranking Democrat on the Senate intelligence committee, said Secretary of State John Kerry gave the panel a more comprehensive picture last week of the U.S. strategy to combat Islamic State, including talks in Vienna to find a diplomatic solution to the Syrian crisis.
However, she said on CBS, "I don't think the approach is sufficient to the job."
