WASHINGTON (AP) — President Barack Obama has delayed his departure for a trip to Kentucky because of the Iran nuclear talks in Switzerland.

Obama had planned to visit a Louisville-based technology company Thursday to discuss job training and Republican plans to repeal the estate tax.

But then word came that an agreement had been reached in the marathon talks over curbing Iran's nuclear program.

It's unclear whether Obama will go ahead with the trip.

After Kentucky, Obama was scheduled to continue on to Hill Air Force Base in Utah for an appearance there on Friday.

The Utah stop would be Obama's first there as president.
