Liberal and conservative activists have launched a website calling for more presidential question-and-answer sessions after President Barack Obama and altHouse Republicans engaged one another last weekend.

Demandquestiontime.com has a number of high-profile backers. Conservatives such as Media Research Center founder Brent Bozell and Americans for Tax Reform President Grover Norquist have signed on, as have liberals like Ana Marie Cox and Daily Kos founder (and The Hill columnist) Markos Moulitsas.

"The exchanges [with House Republicans] were substantive, civil and candid. And in a rare break from our modern politics, sharp differences between elected leaders were on full public display without rancor or ridicule," the site says. "It is time to make Question Time a regular feature of our democracy."

The site has a petition visitors can sign, which has 48 signatures so far.

Backers of the effort will not have to wait long. Obama will speak to Senate Democrats in a televised question-and-answer session on Wednesday morning.
