Todd Palin - the husband of former Alaska governor and vice-presidential candidate Sarah Palin - has been hospitalized following a snowmobile accident in Alaska.
The extent of Palin's injuries is unknown, but NBC News has described his condition as "very serious."
Palin was scheduled to speak at a Donald Trump rally in Florida this afternoon, but she has canceled her appearance in order to return home and be by her husband's side.
The Palin's eldest son, Track Palin, was arrested on domestic violence charges in January and was scheduled to be in court today.
It is not yet known if his father's injuries will cause the start of Track's trial to be delayed.
Sarah Palin's social media followers became concerned when she abruptly canceled her appearance just minutes before she was scheduled to take the stage today.
The Trump campaign issued the following statement moments ago:
"Todd Palin was in a bad snow machine accident last night and is currently hospitalized. Governor Palin is returning to Alaska to be with her husband and looks forward to being back on the campaign trail soon. Mr. Trump's thoughts and prayers are with the Palin family at this time."
We will have updates on this story as more information becomes available.
