"After several hours, the senators were evacuated by American troops and returned overland to Bagram Air Base, and left for their next scheduled stop in Ankara, Turkey," the Kerry statement said. "Sen. Kerry thanks the American troops, who were terrific as always and who continue to do an incredible job in Afghanistan."
The lawmakers were on a trip this week that included stops in India, Turkey and Pakistan, where they observed the elections earlier this week.
Kerry and Biden are Democrats from Massachusetts and Delaware, respectively, and the Republican Hagel is from Nebraska.
