'Case Disrupted' Ahead of Pope Francis Visit to US, Says House Homeland Security Chair Rep. Michael McCaul was interviewed on "This Week."

 -- The chairman of the House Homeland Security Committee expressed his concern today about security ahead of Pope Francis’s visit to the United States later this month, adding that authorities have already “disrupted one particular case.”

Rep. Michael McCaul (R-TX) didn’t offer specifics on the case he said was disrupted, only saying he had been briefed by the Secret Service. The pope is scheduled to arrive in the U.S. later this month and will visit New York, Washington, D.C., and Philadelphia.

“The Pope is a very … passionate man. He likes to get out with the people and with that comes a large security risk,” McCaul told Martha Raddatz on ABC’s “This Week.” “We are monitoring very closely threats against the pope as he comes into the United States. We have disrupted one particular case in particular, but as that date approaches, I think we’re all very, being very vigilant to protect him as he comes into the United States.”

When asked about the case, the Secret Service and a spokesperson for McCaul declined comment.
