former united states attorney and university of alabama law school professor, also a msnbc legal contributor. and harry litman. harry, last week we learned new details about specific lawmakers like jim jordan who were revealed to have been involved. we also just learned that stop the steal organizer ali alexander told the committee that he spoke with paul gosar, potentially mo brooks, and andy biggs prior to the capitol riot. harry, when can we expect the committee to subpoena some of these people? does the fact that they re members of congress give them some legal protection in some way from being subpoenaed? it would often give them a kind of diplomatic protection. and it feels like a third rail, katie. but i think they re going to step on it, and soon.
