The midsized Washington-based law regulatory firm Keller and Heckman is advising Peloton Interactive Inc. in a clash with a U.S. consumer product safety regulator over its warning that a treadmill made by the exercise equipment and fitness company poses an urgent public danger.

The U.S. Consumer Product Safety Commission on Saturday urged consumers to stop using the Peloton Tread+ machine. The agency cited "multiple incidents of small children and a pet being injured beneath the machines." At least one child death has been linked to a Peloton Tread+ machine. The company has refuted the federal agency's warning.

Keller and Heckman partner Sheila Millar is on the team representing Peloton. Millar focuses on regulatory, compliance, policy and crisis management matters that often involve the consumer product agency, the Federal Trade Commission and state attorneys general.
