Blumenthal is vying for Christopher Dodd's U.S. Senate seat.
According to the times, Blumenthal spoke about serving in Vietnam during a ceremony honoring veterans.
"We have learned something important since the days that I served in Vietnam," Blumenthal said to the group gathered in Norwalk in March 2008.
In an interview with the Times on Monday, the attorney general said that he had misspoken about his service during the Norwalk event and might have misspoken on other occasions.
Blumenthal's Senate Campaign Manager released a statement saying:
"The New York Times story is an outrageous distortion of Dick Blumenthal's record of service. Unlike many of his peers, Dick Blumenthal voluntarily joined the Marine Corps Reserves in 1970 and served for six months in Parris Island, SC and six years in the reserves. He received no special treatment from anyone.
Dick has a long record of standing up for veterans. Tomorrow, veterans will be standing up with Dick."
