Acid reflux is causing President Obama's sore throat

BETHESDA, Md. (AP) -- The White House says acid reflux is causing President Barack Obama's sore throat.

In a statement released by the White House, Obama's physician says a CT scan conducted Saturday afternoon on the president was normal. Dr. Ronny Jackson says Obama's symptoms are consistent with soft tissue swelling related to acid reflux. Obama has been complaining of a sore throat.

Jackson says that on Saturday morning he supervised a fiber optic exam of Obama's throat by an ear, nose and throat specialist.

That exam revealed swelling in the back of the president's throat.

Jackson says he and the specialist then determined that a follow-up CT scan should be the next step.

Obama underwent the CT scan at a military hospital just outside Washington.
