Todd Palin is hospitalized in the intensive care unit after a snowmobile accident Sunday night, reports NBC News. His condition is not known, but a source tells NBC that the crash itself was "very serious." The news surfaced after Sarah Palin canceled a campaign event on behalf of Donald Trump on Monday afternoon in Florida. She's "been on the phone with doctors and family all morning" and has booked a flight back to Alaska, reports the Daily Caller. "Governor Palin is returning to Alaska to be with her husband and looks forward to being back on the campaign trail soon," says a Trump campaign statement. "Mr. Trump's thoughts and prayers are with the Palin family at this time." (More Todd Palin stories.)
