WASHINGTON (CNN) -- Sen. John McCain's, R-Arizona, presidential campaign fired back Friday at former Sen. John Edwards, D-North Carolina, who criticized McCain for his continued support for military involvement in Iraq.

"If John Edwards believes America can't win the war in Iraq, he should convince his Democratic counterparts, including Sens. Obama and Clinton to immediately cut off funding for the war and bring the troops home," Danny Diaz, a spokesman for McCain told CNN. Diaz was speaking about Sen. Barack Obama, D-Illinois, and Sen. Hillary Rodham Clinton, D-New York. McCain, Clinton, Edwards and Obama are all running for president.

On Thursday Edwards said of McCain's Iraq stance, "He was wrong about the surge, he's been wrong about Iraq and he's wrong in the way he describes what's happening in Iraq right now."
