U.S. Senator Ed Markey and U.S. Representative Seth Moulton are trading jabs in the first debate for the Massachusetts Senate primary. 

Wednesday, the two Democrats traded sharp attacks at WWLP 22News in Chicopee. 

They sparred over age, health care, transgender athletes and personal finances.  Markey questioned Moulton's ties to military contractors, while Moulton argued Democrats need generational change. 

The September 1st primary is approaching, and two more debates are scheduled.
