ThinkProgress was an American news website. It was a project of the Center for American Progress Action Fund (CAP Action), a progressive public policy research and advocacy organization. Judd Legum founded ThinkProgress in 2005. The site's reports have been discussed by mainstream news outlets and peer-reviewed academic journals. Its climate section, formerly known as Climate Progress, was founded by Joe Romm. CAP Action is seeking a new publisher for the site but shut it down in September 2019.
