I didn’t see it on the schedule when I looked earlier. Looks like it’s on C-SPAN3. Unfortunately, not on C-SPAN Radio, which is the only way I could follow it at work. Instead, they’re carrying the hearing on (hetero)sexual assaults in the military.
Actually, looks like I was wrong looking again. It only lists the IRS hearing as a C-SPAN.org event. I don’t see any indication of TV coverage.
