GREENSBORO, N.C. -- A Greensboro museum is receiving threats after refusing to shut down for a presidential candidate.

In September, the International Civil Rights Center and Museum denied a request from the Donald Trump campaign to close for "5 to 6 hours" for a private tour for the Republican presidential nominee.

Museum co-founder Earl Jones says that's a request the museum would have denied for anyone, even Trump's opponent Hillary Clinton.

"We wouldn’t relinquish control of the museum to anyone," Jones said. "We have control of the museum, we have professional tour guides, and [the Trump campaign] wanted complete control of the museum for 5 to 6 hours, and didn’t want our staff to participate or guide the tours."

After news of the museum's refusal, Jones says, several racially charged and threatening calls and emails started coming to the museum.

"We have received some phone calls that were outrageous and outlandish," he said. "Racial slurs and phone calls where conduct reflected deplorable language directed toward our staff."

Jones says some of the anonymous callers threatened to shoot staff members, or even burn the museum to the ground.

"I feel like that’s a small group of people that doesn’t represent the fine people of Greensboro, and the state of North Carolina, or the nation, for that matter," Jones said.

Museum officials say, for every negative response, they've received 10 positive responses about their decision. They also say the museum has seen an uptick in donations since their decision went public.

The Trump campaign has not issued a statement for this story, though a representative for the campaign's North Carolina office told WFMY News 2 one is in the works.
