Mary McCormack replaces Joe Mantegna as National Memorial Day Concert co-host in last-minute change

The West Wing actor Mary McCormack is stepping in for Joe Mantegna to co-host the National Memorial Day Concert in a last-minute change.

McCormack, 57, will lead the 37th annual concert with Forrest Gump actor Gary Sinise, after Mantegna, who has hosted the annual concert for nearly two decades, dropped out of PBS’s TV event due to what the Tony-winning actor described as “unforeseen circumstances.”
