A reporter for The New York Times was ejected from a Trump campaign at a pizza parlor in Waukee, Iowa, on Friday.
The reporter, Trip Gabriel, tweeted that when Trump visited a Pizza Ranch restaurant he "was ejected, though about 20 other TV & digital reporters remained."
“It’s a private event. You have to go,’’ a local police officer told him.
The incident comes two days after Gabriel published a story in the Times about the business mogul's Iowa operation, calling Trump's ground game in the Hawkeye State "partly an afterthought" and "amateurish and halting, committing basic organizing errors."
Trump has clashed with the New York Times and other newspapers before.
At the GOP primary debate on Thursday night, Trump attacked the paper for quoting him as saying he would impose a 45 percent tariff on goods imported from China.
"That's wrong. They were wrong. It's the New York Times, they are always wrong," he said.
After The Des Moines Register called on him to end his campaign in a July editorial, he responded by refusing to issue press credentials to the paper's reporters.
