Washington (CNN) -- Will it be a boycott or a chaperone? House Democrats remained undecided Friday on whether they would join a select committee created by majority Republicans to investigate the Benghazi terror attack. The chamber's Democratic leader, Rep. Nancy Pelosi of California, described a split in her caucus over the matter in remarks to reporters that lambasted Republicans for what she called a "political stunt," "subterfuge" and a "diversionary tactic." Options under consideration include participating as a minority bloc, which Republicans have proposed; having a lone member take part to register disapproval but maintain a presence, or rejecting the entire process as a partisan witch hunt.
