New Jersey: Tracy Morgan is suing Walmart over last month's highway crash that seriously injured him and killed a fellow comedian.

The lawsuit, filed on Thursday in the US District Court in New Jersey, claims Walmart was negligent when a driver of one of its tractor-trailers rammed into Morgan's limousine bus.

The June 7 crash on the New Jersey Turnpike killed 62-year-old comedian James McNair, who went by the name Jimmy Mack.

Comedian Ardley Fuqua and Jeffrey and Krista Millea, who were passengers in the limo, are named as plaintiffs.

Morgan, the former Saturday Night Live and 30 Rock star, suffered a broken leg and broken ribs in the crash. Fuqua is recovering from crash-related injuries.

The truck driver, Kevin Roper, has pleaded not guilty to death by auto and other charges.
