Stop using my son's name: Benghazi victim's mother writes to Donald Trump

Washington: The mother of US Ambassador to Libya J Christopher Stevens, who was killed during a terror attack in Benghazi in 2012, has asked Republican presidential nominee Donald Trump and the party to immediately stop their "opportunistic and cynical" use of her son's death.

"I know for certain that Chris would not have wanted his name or memory used in that connection," Mary Commanday wrote in a short letter to the editor of The New York Times.

"I hope that there will be an immediate and permanent stop to this opportunistic and cynical use by the campaign," she said.

Stevens, 52, is the first US Ambassador killed in the line of duty since 1979.

The Benghazi attack took place on September 11, 2012, when Islamic terrorists attacked the American diplomatic compound, killing Ambassador Stevens and US Foreign Service Information Management Officer Sean Smith.

The Benghazi attacks were frequently mentioned in speeches at last week's Republican National Convention in Cleveland, where speakers used it as a reason presumptive Democratic nominee Hillary Clinton is unfit for the presidency, CNN reported.

Clinton was secretary of state at the time of the attacks.

Some conservatives blame Clinton and the Obama administration for security failures in Benghazi that they blame for the deaths of Stevens and three other Americans.

At one point during the convention, another victim's mother, Pat Smith, spoke before the audience and blamed Clinton for the death of her son, IT expert Sean Smith.
