The Orlando, Florida-based personal injury firm Morgan & Morgan has sued Marriott International in federal court one day after the hotel chain announced it had been the victim of another data breach affecting millions of customers.

On Wednesday, attorneys with Morgan & Morgan filed a proposed class action lawsuit in the U.S. District Court for the District of Maryland. The suit, Springmeyer v. Marriott International, listed Las Vegas resident Pati Springmeyer as class representative, and alleges the company failed to take required steps to protect its customers’ data.
