The White House rejected Iranian President Mahmoud Ahmadinejad’s offer for a public debate with US President Barack Obama. White House Spokesman Robert Gibbs said that Tehran has not displayed seriousness on the nuclear issue.

Ahmadinejad called for Obama to discuss international affairs during a meeting of the UN General Assembly next month. Former President George Bush Jr. rejected a similar offer extended by Ahmadinejad.
