The campaign of Democratic presidential candidate Hillary Clinton says the senator has not changed her position on negotiating with Iran.

A Clinton spokesman said Friday that she would not agree to unconditional talks with the Iranian president, but that the two governments could negotiate.

The clarification comes after the Democratic frontrunner said Thursday that, if elected, she would engage in negotiations with Iran with no conditions.

Clinton argued the United States does not really understand how Iran works and suggested talks with Tehran would be useful.

Her comments were questioned today by fellow senator and rival Democratic presidential candidate Barack Obama. In July, Clinton called Obama's position favoring talks with the Iranian leader naive and irresponsible. She said she would first send envoys to determine if negotiations were wise.

Clinton Thursday also defended her vote last month in favor of a resolution labeling Iran's Revolutionary Guard Corps a terrorist organization. She said the resolution is a way of increasing diplomatic pressure on Tehran.
