Ask the White House began in 2003 as an "online interactive forum" on the White House webiste that "allows you to interact with Bush administration officials and friends of the White House." It is set up as a Q&A where the American public can ask government officials what is on their mind.

This week's guests coincide with Earth Day. Administrator of the U.S. Environmental Protection Agency, Stephen L. Johnson, will host Ask the White House on Friday at 3p ET to discuss Earth Day, and Secretary of the Interior, Dirk Kempthorne will be available on Tuesday, April 24 for national park week.

Any one is invited to submit a question. I did. Even though it says he will discuss Earth Day, I thought I'd ask Johnson for a response to the Supreme Court decision earlier in the month. My question:

Will the EPA move forward with steps to regulate vehicle emissions given the recent Supreme Court decision that found the agency has authority under the Clean Air Act to do so?

In looking at some of the archived transcripts from previous Ask the White House Q&A sessions (topics with officials on Sudan and on Urban Development), there's nothing interactive about it. Although it is touted as 'live' it is definitely not a live chat (if you've ever been on IM with more than a few people you know it can get a little crazy). The format is straightforward Q&A with a few questions that have been hand picked by White House staffers and are more than likely answered ahead of time.

I'm guessing that they'll choose safe questions and respond accordingly with diplomatic answers, and they'll probably take the opportunity to address popular criticisms surrounding the EPA. I am curious to see what questions they field (and if they answer mine). I'll check in on Friday to see and give an update on Saturday.
