Chairman of oversight board tapped by Obama says group concerned about NSA surveillance

The chairman of the group that President Barack Obama says will meet with him to discuss the National Security Agency's secret surveillance program is expressing concerns about the program and says the group will publish a report about its inquiry.

The chairman of the Privacy and Civil Liberties Oversight Board, David Medine, tells The Associated Press that the board has a "broad range of questions" about the NSA's widespread collection of Americans' phone and Internet data. He spoke on Wednesday following a closed-door meeting of the group.

Medine says the board will hold a July 9 public session to listen to expert and public concerns.
