Roger Worthington, leading a $51 billion lawsuit against oil producers on behalf of Multnomah County, Oregon, is facing scrutiny from House Republicans. The lawsuit blames the industry for a 2021 heat wave that killed 69 people. Republicans are investigating alleged efforts to influence judges overseeing climate litigation.

Worthington, known for his past success in asbestos litigation, will be questioned under subpoena. This case is part of a broader legal battle where over two dozen governments seek to hold oil and gas companies financially accountable for climate change. The industry warns of potential tens of billions in costs, and Republicans have proposed legislation to block these lawsuits.

Worthington has accused lawmakers of "throwing Big Oil a bone." Rep. Darrell Issa stated the committee seeks "the truth." Friends of Worthington believe the scrutiny reflects the significant threat his advocacy poses to established power. He previously worked at an Exxon Mobil refinery and has a history of supporting Democratic candidates.
