Sens. Chuck Grassley (R-Iowa) and Mary Landrieu (D-La.) will appear together in an episode of "Dr. Phil" to air Oct. 1.

The two co-chair the Senate Caucus on Foster Youth and will use their segment to discuss adoption and a 2008 bill that provides federal incentives for states to move children out of foster care and into adoptive homes.

Grassley tweeted the news Tuesday.

"Watch DrPhil Oct1 to c intrvu w Grassley/Landrieu on a nonPartisan social issue," he said.

He and Landrieu recorded the spot Sept. 20.
