“All okay. Thank goodness,” the spokeswoman, Andrea Saul, wrote on Twitter.
Saul added the cause of the emergency was apparently “an electrical fire” after the cabin of the plane filled with smoke. Romney’s plane was headed to Los Angeles but landed in Denver, where it was met with emergency vehicles on the runway.
Ann Romney was near Omaha, Nebraska earlier Friday. Her press secretary, Sarah Haley, was also on the plane.
A Secret Service official confirmed the incident.
“We can confirm that a plane carrying Mrs. Romney and two Secret Service personnel did make an emergency landing about 4:25 ET. It was at the Denver airport,” the official said. “Basically what we understand there was some type of smoke in the cabin. All personnel were safe.”
The official could not say who else was on board.
