Jan Stevens, the 77-year-old father of Christopher Stevens, said Sunday that his son’s death should not a political talking point.

“It would really be abhorrent to make this into a campaign issue,” he told Bloomberg.

The U.S. consulate in Benghazi was attacked on September 11 by heavily-armed militants, killing Ambassador J. Christopher Stevens and three other Americans.

Republicans, including Mitt Romney, have claimed the U.S. Department of State contributed to the disaster by failing to provide the consulate with adequate security on the anniversary of the September 11 terrorist attacks. At the vice presidential debate, Rep. Paul Ryan (R-WI) said the Benghazi attack highlighted Obama’s failed foreign policy.

“The security matters are being adequately investigated,” Stevens said. “We don’t pretend to be experts in security. It has to be objectively examined. That’s where it belongs. It does not belong in the campaign arena.”

The U.S. State Department is investigating the incident, which is believed to have been carried out by al Qaeda-linked militants.

Chris, who had worked for both Republican and Democratic presidents, felt very strongly about Secretary of State Hillary Clinton. Chris believed she was “an extremely able person,” according to his father.

Romney has suggested that Obama is trying to cover-up the attack. The White House initially said the attack occurred during a spontaneous protest against an anti-Islam movie. Later, the White House admitted its initial public statements were incorrect, and that no protest had occurred.

Romney said in late September that the Obama administration “want to do their very best to keep the people of American from understanding exactly what happened.”
