Rolling Stones front man Mick Jagger took a shot at President Obama during the group’s Monday night show at the Verizon Center in Washington, D.C.

The Obama administration has had to defend the National Security Agency’s phone and email tracking program since Edward Snowden, a 30-year-old former NSA contractor, shared details about the program and another program, called PRISM, which gathers Internet data on foreign citizens suspected of terror links.

The disclosures have sparked a debate over the proper balance between national security and civil liberties.

Obama has in the past talked about his admiration for Jagger, and he joined the Rolling Stones on stage when the group appeared at the White House concert series in early 2012.
