Afghan president got cash from Iran; U.S. questions motives

Kabul, Afghanistan (CNN) -- President Hamid Karzai of Afghanistan acknowledged Monday he has received cash from Iran and said the United States knows about it and does the same thing in doling out cash.

In response, the U.S. State Department spokesman said the United States does not question Iran's right to give financial assistance to Afghanistan, nor does it question Afghanistan's right to accept it.

"But we remain skeptical of Iran's motives, given its history of playing a destabilizing role with its neighbors," said spokesman P.J. Crowley.
