Warning Democratic Governor Roy Cooper that his state would suffer economically if he blocked the event, Trump demanded in a series of early Monday tweets that Cooper allow "full attendance" to the convention in the state's largest city Charlotte on August 24.
Nominating conventions are typically attended by about 50,000 people, including thousands of media representatives.
President Trump on Monday denied any suggestion that he might want to hold this summer's Republican National Convention at his resort in Doral, Fla., following his threat to move the convention from North Carolina if that state's governor can't guarantee the party will be allowed "full attendance" at the event.
He added: "In other words, we would be spending millions of dollars building the Arena to a very high standard without even knowing if the Democrat Governor would allow the Republican Party to fully occupy the space".
Responding to the president's remarks, Gov. Roy Cooper's spokesperson said local health officials were "working with the RNC and will review its plans as they make decisions about how to hold the convention in Charlotte".

Earlier in the afternoon, prominent activist Tam Tak-chi was arrested during the protest for what police said was unauthorized assembly.
"These national conventions literally take many months to organize and prepare", Pence said. We all want to be in Charlotte.
Vice President Mike Pence reiterated Trump's comments Monday, telling Fox News he looks forward to a swift response from Cooper, and "if need be, moving the national convention to a state that is farther along on reopening and can say with confidence that we can gather there".
Charlotte, North Carolina's biggest city, has had more confirmed coronavirus cases and more deaths from the virus than anywhere else in the state.
Gov. Roy Cooper has eased North Carolina's stay-at-home order but still is urging caution. "We love North Carolina", Pence said.
