Ooooh, this might get interesting

"Tomorrow, Attorney General Eric Holder will testify before the House Judiciary Committee," an email sent this afternoon by the Deputy Press Secretary, House Committee on Oversight and Government Reform announces:

Congressman Issa will press Attorney General Holder on the role of the ATF’s Phoenix office in 'Operation Fast and Furious', a botched gun tracking project which knowingly allowed guns into the hands of drug cartels leading to the death of U.S. Customs and Border Patrol agent Brian Terry.

The testimony will occur Tuesday 5/3/2011 at 10:15 a.m. at 2141 Rayburn House Office Building. It will be webcast live at www.judiciary.house.gov.
Holder under oath; that should lead to some interesting responses to Issa.

Note I did not say 'answers', I'd imagine he's likely to try to avoid many of those.
