Democrats to join Benghazi select committee

 (CNN) -- House Democratic Leader Nancy Pelosi says she will appoint members to the House select committee on the deadly 2012 Benghazi terror attack. The panel will be comprised of seven Republicans and five Democrats.

Democrats have been pressing for a greater role in how the committee operates.

A senior GOP aide told CNN that "we have offered assurances on committee procedures, but no substantive changes that could hurt the investigation."

The following Democratic members will serve on the panel: Reps. Elijah Cummings of Maryland, Adam Smith of Washington, Adam Schiff and Linda Sanchez of California, and Tammy Duckworth of Illinois.
