Just minutes before its scheduled start time, the Trump campaign advised that the event had been cancelled.
A statement from Trump's campaign team said Palin is heading back to Alaska to be with her husband.
Alaska Gov. Sarah Palin, who endorsed Trump back in January, let loose on the protesters who have been interrupting the real estate mogul's rallies, calling their actions "petty punk-a- little thuggery".
In the appearance, Palin thanked the public for their prayers as her husband recovers.
In a Facebook posting, Sarah Palin called her husband the "toughest guy" she knows, adding that she was flying home to Alaska.
"If Todd Palin were in that room, frankly, if Sarah Palin were in the room - forget about Todd, especially now", Trump said, seeming to refer to Palin's hospitalization. Gretchen Carlson tried to get clarification that the live feed was in fact happening, since reports indicated that Palin was leaving Florida immediately to return to Alaska to be with her husband and family.
Before returning to Alaska, Palin made an unscheduled appearance at Trump's event in Tampa, Florida, today.
Todd Palin is an avid snowmobiler and four-time champion of the Iron Dog, the longest snowmobile race in the world at more than 2,000 miles. "You know, your prayers have meant so much to our family over the years and I've not thanked you enough for providing us that shield of faith".
Since then, her influence has waned, but she remains a popular figure in conservative circles as an iconoclast who often butts heads with the party leadership.
The incident took Palin temporarily off the 2016 Republican primary trail, where she was campaigning for frontrunner Donald Trump.
