(Reuters) -Shares of health insurers such as UnitedHealth (NYSE:) and CVS Health (NYSE:) fell on Wednesday after a Wall Street Journal report said a bipartisan group of lawmakers was set to introduce legislation to break up pharmacy-benefit managers.

The Senate bill, sponsored by U.S. Senators Elizabeth Warren and Josh Hawley, will force companies that own health insurers or pharmacy-benefit managers to divest their businesses operating pharmacies within three years, the report said.

Pharmacy-benefit managers negotiate prescription drug prices between insurers, pharmacies and drugmakers, and directly reimburse pharmacies for prescription drugs included under their agreed upon terms.

UnitedHealth shares fell 5%, while CVS Health dropped 4.3% and Cigna (NYSE:) slipped 4.4%.

Peers Elevance, Humana (NYSE:) and Centene (NYSE:) fell between 1% and 3%.

Shares of insurers have come under pressure after Brian Thompson, the CEO of UnitedHealth’s health insurance unit, was fatally shot outside a Manhattan hotel last week.
