The watchdog group American Oversight sued the Trump administration to learn whether a top healthcare official violated ethics rules by working on issues related to her former consulting clients.

The federal lawsuit filed Friday focuses on the work of Centers for Medicare & Medicaid Services, or CMS, Administrator Seema Verma. She used to head the healthcare consulting firm SVC Inc., which had contracts with states such as Indiana, Arkansas, Iowa, and Kentucky. While at the firm, she worked closely with then-Indiana Governor Mike Pence to create the state’s Medicaid expansion program.
