Ask questions for Roll Call’s fifth Twitter Q&A, to take place Thursday afternoon.

The latest edition is with Stu Rothenberg, a Roll Call columnist who is best known as the editor of the Rothenberg Political Report. His latest column questions the wisdom of buzz suggesting Rep. Gabrielle Giffords, who is recovering from a gunshot wound, could mount a Senate bid.

Stu is a Twitter newbie, and his handle is @stupolitics.

Submit questions via Twitter here. We will post a transcript as well.
