Seventy-five members of the Senate sent a letter on Sept. 14 to European Union foreign affairs chief Catherine Ashton urging the EU to designate Hizballah a terrorist organization.
The letter was spearheaded by Sens. Robert Casey (D-PA) and James Risch (R-ID).
"We believe the evidence and dangers posed by Hezbollah and Iran to all European citizens are serious enough to designate Hezbollah a terrorist organization," the letter states. "A terrorist designation from the EU would not only subject Hezbollah to further sanctions, but would also send a message to Hezbollah that Europe and the United States will not tolerate its dangerous and violent tactics."
There are currently two companion letters circulating in the House addressed to senior level EU officials.
The United States has listed Hizballah as a terrorist organization since 1995.
