A day after endorsing Donald Trump, Sarah Palin failed to appear as expected at a campaign rally for the GOP frontrunner Wednesday morning.
Trump supporters in Norwalk, Iowa, had been advised on Tuesday that Trump would appear "with a very special guest" in the wake of the high-profile endorsement by the former Alaska governor.
But in Norwalk, Trump gave a relatively standard stump speech -- heavy on criticism of GOP rival Ted Cruz -- without being joined by the onetime vice-presidential candidate at all.
The Trump campaign has not yet responded to a request for comment from NBC News.
Palin suggested in a Facebook post that talk of her absence was simply being "spun up" by the media.
Palin shared the stage with Trump on Tuesday night in Ames, Iowa, to announce her endorsement of the real estate mogul. In a sometimes disjointed address to the crowd, Palin said Trump is "going rogue left and right."
"Are you ready for a commander-in-chief, you ready for a commander-in-chief who will let our warriors do their job and go kick ISIS ass?" she said.
Palin's son is also in the headlines after his arrest Monday night on domestic abuse charges in Wasilla, Alaska.
Trump is scheduled to hold a campaign rally at Oral Roberts University in Tulsa, Oklahoma, later Wednesday.
