The Post is starting a new livechat series called “Congress Calls,” which will feature weekly online chats with members of Congress. Each week, a different member of the Senate or House of Representatives will answer reader questions about the economy, the wars or anything else that comes up.

As we get started, we want to hear from you: Which member of Congress do you want to chat with?

Write your answer in the comments. If another reader has already written the name of the member you want to chat with, hit the “recommend” button at the bottom of their comment.

The person with the most recommends will be September’s “Congress Calls” reader selection.

We can’t guarantee that member will agree to chat with us. But we promise to try our best to book that person for sometime in September.

“Congress Calls” will start Wednesday, Sept. 7. Chats will generally take place Wednesdays at 1 p.m., although timing may vary on a weekly basis due to the congressional voting schedule.

Update: Rep. Raul Grijalva (D-Ariz.), the co-chairman of the Congressional Progressive Caucus, will be the first member of Congress to participate in “Congress Calls.” Submit your questions for Grijalva (and vote on questions from other readers) here.
