The committee has arranged for testimony from Hoyer, D-Md.; House
Parliamentarian John Sullivan ; Rep. Michael R. McNulty , D-N.Y., who was in the Speaker’s chair at the time; and several staff members. All the witnesses have already been interviewed privately.

Rep. Bill Delahunt , D-Mass., chairman of the special panel, predicted the hearing would last an entire day.

Delahunt and his Republican counterpart, Rep. Mike Pence of Indiana, recently requested $150,000 to complete their work, which will include an extensive report with recommendations to change House rules.
