Republican mega-donors Charles and David Koch are launching a seven-figure ad campaign to call on Congress to pass a lasting solution to protect Dreamers from deportation.

The LIBRE Initiative and Freedom Partners Chamber of Commerce, two groups within the powerful Koch network, announced the national, multiplatform advertising campaign campaign Tuesday night. The ad, featuring former presidents Barack Obama, Bill Clinton, and George W. Bush, will air nationally on Sunday, beginning with a spot on NBC’s Meet The Press.
