Donald J. Trump said on Friday that he had bought NBC’s stake in the Miss Universe Organization, the group that produces the beauty pageant, which the network refused to broadcast this summer.

NBC backed out of broadcasting the Miss USA contest in July after comments by Mr. Trump, an owner of the organization, about immigrants stoked widespread outrage. Univision likewise backed out of its broadcast, which prompted Mr. Trump to sue the Spanish-language cable channel for $500 million.

Mr. Trump also said on Twitter that he had “settled all lawsuits against them,” referring to NBC, but it was not immediately clear if he had actually ever sued NBC. He had said that he intended to. NBC confirmed that Mr. Trump had bought the network’s stake in the pageant but declined to comment on whether it had been involved in a lawsuit with him.

Previously, Mr. Trump owned 49 percent of the Miss Universe Organization, according to Mr. Trump’s lawsuit against Univision. Now, according to his statement on Twitter, Mr. Trump owns it entirely.
