I think their voting on whether or not to subpoena Steve Bannon. It seems that the democrats got mad that the Chairman was going to have a contempt hearing later because Strzok refused to answer a question. Then some democrat said that Bannnon was not cited, so they want to bring him back to see if they can get a contempt citation. Just a ridiculous attempt to slow the hearing down.
I hope they have ALL day, as Strozk tires he'll make mistakes once unscripted.
