In a message on Twitter Friday, Sen. Chris Murphy (D-Conn.), wrote: “If the primary purpose of the killing of Mr. Fakhrizadeh was to make it harder to restart the Iran nuclear agreement, then this assassination does not make America, Israel or the world safer.”

Former CIA director John O. Brennan, a strong Trump critic, tweeted that the attack was “a criminal act & highly reckless.”

“It risks lethal retaliation & a new round of regional conflict,” he wrote. “Iranian leaders would be wise to wait for the return of responsible American leadership on the global stage & to resist the urge to respond against perceived culprits.”
