NEW YORK - Funeral services for U.S. Sen. Frank Lautenberg will be held Wednesday at a New York City synagogue.

The 89-year-old Lautenberg, a multimillionaire businessman and the last World War II veteran remaining in the Senate, died early Monday at a New York hospital after suffering complications from viral pneumonia.

The funeral is planned for 11:30 a.m. Wednesday at the Park Avenue Synagogue in Manhattan.

Lautenberg, who lived in Cliffside Park, is survived by his wife, Bonnie, and four children from his first marriage, which ended in divorce in 1988.

Gov. Chris Christie has ordered the state’s flags to fly at half staff Wednesday.

Lautenberg’s body will be ceremonially placed aboard an Amtrak train bound for Washington, D.C. He was a longtime advocate of the railroad.

Lautenberg’s casket will be made available for public viewing on the Capitol grounds. Lautenberg will be buried Friday at Arlington National Cemetery.
