Is it better for former Secretary of State Hillary Clinton if Democrats boycott or participate in the new House investigation of the Benghazi attacks?

That question is central to Minority Leader Nancy Pelosi’s decision whether to appoint Democratic members to the House select committee.

Several Democrats have urged Pelosi not to participate in the committee, saying it is unwise to lend an air of legitimacy to an investigation they have derided as a political witch hunt. But others, particularly those close to Clinton, believe that having Democrats on the panel is the only way to ensure both sides of the story will be told.

The Benghazi hearings are likely to become televised spectacles, so the thinking in Clinton world is that it’s better to have Democrats join in the questioning in hopes of balancing the proceedings, ABC News has learned.
