Former Sen. Joe Lieberman (I-CT) on Sunday blasted President Barack Obama for asking for Congress’ approval before launching an attack on Syria over the President Bashar al-Assad’s alleged use of chemical weapons.

“I was looking back,” Lieberman told Fox News host Chris Wallace. “Over my 24 years, never saw anything like it.”

The former senator insisted that the president now had authority to act and that it would be “catastrophic” if Congress did not give the green light to attack Syria.

Lieberman said that he would urge lawmakers — including his “amigos,” Sens. Lindsey Graham (R-SC) and Sen. John McCain (R-AZ) — to approve an action in Syria.

“I’m sure that our enemies are cheering now as a result of this decision because they realize it’s not clear the president will get authority, and our allies are worried,” he concluded. “That’s why, again, this resolution or something like it has to pass Congress.”
