Sen. Arlen Specter (D-Pa.) on Thursday took a wait-and-see approach on the issue of sending additional U.S. forces to Afghanistan.

The Obama administration sent additional troops in February but has indicated it will wait until the commander of U.S. and NATO forces in Afghanistan Gen. Stanley McChrystal issues his recommendation on troop levels there.

Specter tweeted:

Before committing more troops, we must determine whether securing Afghanistan is essential to prevent al-Qaida from launching another attack

Senate Republicans and Democrats have become divided whether or not to deploy more troops. Armed Services Committee chairman Carl Levin (D-Mich.) stated his opposition to the idea, while the committee's top Republican John McCain (Ariz.) said he favors increasing the force's size.

The Republican-turned-Democrat appeared to take a similar tack as the White House, hesitating to opine on the issue before learning more information about the scenario.
