ProPublica, the not-for-profit news website focusing on investigative journalism, has gone live.

Editor-in-chief Paul Steiger and managing editor Steve Engelberg welcomed readers to the site yesterday in an introductory post, saying the site would be committed to covering news that had slipped under the radar and to probing further into existing stories.

“Today, we take our first concrete step in building an investigative publishing platform that will produce original stories focusing on betrayal of the public trust and abuse of power.”

The site will feature original content, including long-term investigations working with other media partners, alongside analysis of current campaigns and news and an aggregation of investigative journalism online.

The launch follows the latest phase in ProPublica’s recruitment with seven new additions to its staff bringing the total to 20 out of a planned 27.
