Last fall the U.S. Department of Justice proudly claimed a major victory for its Health Care Corporate Fraud Strike Force when it nailed Tenet Healthcare Corp. for a multimillion-dollar kickback and bribery scheme. It was the strike force's first major victory—it also may have been its last.

That's at least in part because the DOJ, under the Trump administration and new U.S. Attorney General Jeff Sessions, has announced new priorities: violent crime, drugs and illegal immigration.

In restructuring to focus on those priorities, the DOJ has gutted the Health Care Corporate Fraud Strike Force, according to at least two high-level sources who worked at the Justice Department until recently. The sources declined to be named, as being identified could affect their current jobs and clients.
