Donald Trump has been mocked by his Republican rivals at a televised debate in Iowa, after quitting the event in a row with Fox News.
He decided to withdraw after the broadcaster refused to drop host Megyn Kelly, whom Mr Trump accused of bias.
The billionaire held a rally nearby, in honour of war veterans, that threatened to overshadow the debate itself.
On Monday, voters in Iowa are due to pick their presidential nominee for each party.
Days ahead of that critical test, Mr Trump’s absence on the stage in Des Moines was keenly felt by his seven rivals in the race to be Republican presidential nominee.
Texas Senator Ted Cruz addressed it with humour in the opening minutes by throwing mock insults at his rivals.
“I’m a maniac and everyone on this stage is stupid, fat and ugly, and Ben [Carson], you’re a terrible surgeon,” he said.
Former Florida Governor Jeb Bush also poked fun at the billionaire businessman, who has often tormented Mr Bush in previous debates.
“I kind of miss Donald Trump; he was a teddy bear to me,” he said with smile.
