Donald Trump’s campaign was having a little trouble with Wichita’s name on Friday morning.

The presidential candidate misspelled Wichita in a tweet, prompting a wave of responses from locals and others.

“My friend, & great businessman, Phil Ruffin is speaking today in Kansas for me at the Witchita Pachyderm Club,” Trump tweeted around 8 a.m. from his account, @realDonaldTrump. “He lives there and loves it!”

His campaign later misspelled both Wichita and Kansas in a news release announcing that Trump would come to the city for the caucus on Saturday.

“The Donald J. Trump for President Campaign has just announced it will be in Witchita, Kanasas for a major rally on Saturday prior to Caucus,” the news release read.

Trump’s tweet, which featured a common misspelling of Kansas’ largest city, set off a wave of responses, sarcastic and otherwise:

“Where’s Witchita?” Joel Mease tweeted.

“Bro, it’s Wichita,” tweeted Luke Ranker. “Witchita is in Oz.”

And Chris Lilly tweeted: “‘Witchita’ is pretty great. Impossible to get a hotel on Halloween though.”

Trump events last month in Oklahoma misspelled both Tulsa and Oklahoma, the Tulsa World reported.
