Hearing kicks off at 8 p.m.
Thursday's hearing, the first of six scheduled in June, is the culmination of an 11-month-long investigation by the House select committee.
The nine-member panel has collected more than 140,000 documents and 1,000 witness interviews throughout the course of the investigation, and members have promised to introduce never-before-seen videos and exhibits they say will shock the public.
