The New York Times reports:
What we’re expecting to see: The seven members of the House will continue delivering their opening arguments, building on the case against the president that they began on Wednesday. After spending about eight hours in session on Wednesday, of a maximum of 24, they have time to flesh out their case on Thursday.
When we’re likely to see it: Managers are expected to take the floor at 1 p.m., and are likely to stay for another eight hours, wrapping up about 9:45 p.m.
As House managers proceed on Thursday, a clearer picture may emerge of how much of the now-familiar case against the president is left to cover, and how thoroughly they intend to dive back into the details of the House impeachment inquiry.
