Rep. Donald Payne Jr. (D-N.J.), who represented New Jersey in the House for more than a decade, has died at the age of 65.

New Jersey Gov. Phil Murphy (D) confirmed Payne's death in a statement on Wednesday.

"Tammy and I are deeply saddened by the tragic passing of our friend, and a steadfast champion for the people of New Jersey, Congressman Donald Payne, Jr.," he wrote.

Payne suffered what his office called a "cardiac episode" related to complications from diabetes more than two weeks ago and had been hospitalized since.

He had served in Congress since 2013, representing New Jersey’s 10th Congressional District, which covers parts of Essex, Hudson and Union counties.
