Multiple US service members were killed Wednesday in a suicide attack in Northern Syria.
The bombing appears to have been carried out by the Islamic State.
The same morning, Vice President Mike Pence delivered a speech in which he celebrated the demise of ISIS.
"We're bringing our troops home, the Caliphate has crumbled and ISIS has been defeated," Pence declared.
"Now we'll stay in the region and we'll stay and fight to make sure that ISIS does not rear its ugly head again."
