Ask questions for Roll Call’s ninth Twitter Q&A, to take place Thursday around 1 p.m.

The latest edition is with Politics Editor Lauren Whittington. She’s a walking encyclopedia of facts about Congressional races and knows a lot about sports, too.

Submit questions directly to @rollcall via Twitter here, and Lauren (@l_whittington) will answer them this afternoon. We will post a transcript as well.
