Former CIA operative Bob Baer told CNN’s Jake Tapper today that ISIS cells already exist in the United States and are capable of striking.

CNN reports:

“The people who collect tactical intelligence on the ground, day-to-day – and this isn’t Washington – but people collecting this stuff say they’re here, ISIS is here, they’re capable of striking,” said CNN national security analyst and former CIA operative Bob Baer.

“They don’t know what their plans and intentions are. But it’s a definite concern,” said Baer.

U.S. intelligence agents are keeping an eye on suspected ISIS militants who they believe have come across the Mexican border, or are American citizens that have come back from Syria, says Baer.

Speaking of the Mexican border, Judicial Watch has been trying to draw attention to a federal bulletin warning of Islamic terrorist groups operating in the Mexican border city of Ciudad Juarez and planning to attack the United States with car bombs.

Video of Tapper’s interview with Baer is available at CNN’s website.
