WASHINGTON — Every member of the House Intelligence Committee signed a letter to President Barack Obama on Thursday urging him not to pardon Edward Snowden, the former National Security Agency contractor who prompted an overhaul of government surveillance programs after he leaked stolen records about the agency in 2013.

The letter, signed by 23 members of Congress, comes as a new movie about Snowden is released. Civil liberties groups are pushing for the president to pardon Snowden in his final months in office, although the White House has shown no sign of agreeing to this request.
