(CBS News) A plane carrying Ann Romney made an emergency landing in Denver Friday after the plane's cabin filled with smoke, CBS News has learned.

According to the Romney campaign, emergency vehicles met passengers on the tarmac upon arrival. Ann Romney spoke with her husband, Republican presidential nominee Mitt Romney, as soon as the plane landed.

The campaign said none of the passengers were hurt. 

Shortly after the plane landed, Romney spokesperson Andrea Saul tweeted a photo of firefighters boarding the plane, pictured at left.

The apparent cause of the emergency landing was an electrical fire, according to the campaign. The plane was en route from Omaha to Santa Monica, California. 

"A Canadair Challenger 601 charter flight operated by World Wide Jet, diverted to Denver today at about 2:40 p.m. MDT after the pilot reported smoke in the cockpit. The flight was en route from Omaha, NE to Santa Monica, CA. The aircraft landed safely on runway 35L and passengers exited the aircraft via stairs on a taxiway. No injuries were reported," the FAA said in a statement.

Sarah Haley, Ann Romney's press secretary, described the incident on Twitter: "Our plane made an emergency landing because of smoke in the cabin. Everyone is safe. Don't need any caffeine to wake me up now!"
