According to Torricelli, "it is clear Iraqi forces were involved" and also likely that Iran's government took part, he said, because "many of the people who were involved spoke Farsi."
"This is about murder, but it's also about the credibility of the U.S. government," he said.
Ridge praised the MEK as "a group that has the undying enmity and hatred of the mullahs in Iran." He lamented that "the mullahs [of Iran] have perhaps more influence in Iraq than the country that lost several thousand" troops to depose Hussein.
"There needs no argument," he said, "it's about getting them to a safe haven as we promised."
Freeh, who left office in 2001 after nearly eight years leading the FBI, said, "if you Google 'attack on Ashraf' it's very hard to find the attack from Saturday" because of earlier attacks.
"We need to get these people out of there immediately," he said. "It's not a coincidence that it happened over the Labor Day weekend when everyone's distracted by Syria."
Mukasey told participants that the Iraqi government removed blast walls and banned sandbags and helmets at Camp Liberty, preventing MEK members from passively defending themselves.
Kennedy said "it's inconceivable to me that they are not a major priority." The eight-term Democrat, who left Congress in 2011, said the weekend attack presented "the same issue as in Syria." President Barack Obama's plan to conduct punitive air strikes there, he said, is intended to warn Iran about its behavior, as should the U.S. in Iraq.
A letter signed by the prominent conference call participants, as well as former New York City Mayor Rudy Giuliani and former Gov. Howard Dean, D-Vt., demands U.N. peacekeepers to protect the MEK camp residents until they can be hastily resettled elsewhere.
"Several of us have sought to meet with you to present these concerns and to avoid committing these words to paper," the letter to Secretary of State John Kerry, drafted by Torricelli, says. "You've chosen not to meet. We have corresponded with your staff and often have not had the courtesy of a reply."
