A federal judge in Maryland has appointed 14 lawyers to lead class actions brought by consumers over Marriott Inc.'s data breach last year.

Judge Paul Grimm of the U.S. District Court for the District of Maryland appointed the leadership team, as well as others to lead cases against Marriott brought by financial institutions and shareholders, following a hearing on Monday. Among those appointed are three veteran data breach lawyers as co-lead counsel: Andrew Friedman, a partner at Cohen Milstein Sellers & Toll in Washington, D.C.; Amy Keller of Chicago's DiCello Levitt; and James Pizzirusso, a partner at Hausfeld in Washington, D.C.
