Ask questions for Roll Call’s eighth Twitter Q&A, to take place Friday afternoon around 1:30.

The latest edition is with Ambreen Ali of Congress.org. She covers grass-roots activism and has been writing lately for Roll Call on the tea party, and she covered Rep. Peter King’s Homeland Security Committee hearings on the radicalization of Islam.

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