Gen. David Petraeus, commander of the U.S. Central Command, will testify next week before the Senate Armed Services Committee on Afghanistan, the committee announced Tuesday.

News of Petraeus’ visit next Tuesday comes just a day after the nearly nine-year war in Afghanistan officially became the longest war in U.S. history — a fact that has reignited calls from liberal lawmakers to cut off war funding and bring the troops home.

“The war in Afghanistan has now surpassed the number of years we spent in Vietnam, making it the longest war in U.S. history,” Rep. Dennis Kucinich (D-Ohio) said. “This grim landmark must serve as an awakening for the human and financial costs of the war.”

During last week’s Senate debate on the $33 billion war supplemental, Sen. Russ Feingold (D-Wis.) failed to attach an amendment that would have imposed a timeline for withdrawal. House and Senate lawmakers are hashing out the measure in conference.

“This supplemental will add some $30 billion more to the nearly $300 billion we’ve already spent in Afghanistan, with no end in sight,” Feingold said. “This cannot go on and is yet another reason why a flexible timetable for drawing down our troops in Afghanistan is necessary and appropriate.”
