McCain: More troops needed in Afghanistan

Sen. John McCain says more U.S. troops are needed in Afghanistan, insisting that the longer it takes to send them, "the more Americans will be put at risk."

The Arizona Republican told CBS' "Early Show" on Wednesday that the strategy to defeat insurgents in Afghanistan was in place, and said President Barack Obama was "very strong" in March about what needed to be done, AP reported.

Now, McCain says, "It's clear we need additional troops."

Critics at the Pentagon and on Capitol Hill have called on Obama to fulfill an anticipated request for more troops from the top U.S. commander in Afghanistan, Army Gen. Stanley McChrystal. White House officials, however, say they are unsure that a troop increase in Afghanistan will help in the fight against al-Qaida terrorists.
