WASHINGTON (AP) — House Democrats will participate in the special, Republican-led select committee investigating the deadly 2012 attack in Benghazi, Libya, despite serious concerns within the party that the inquiry is an election-year ploy to energize core GOP voters.

Minority Leader Nancy Pelosi announced on Wednesday that she will appoint the full complement of five Democrats on the 12-member panel, tapping lawmakers who have been deeply involved in previous congressional investigations of the Sept. 11, 2012, assault on the U.S. diplomatic outpost.
