Media mogul Rupert Murdoch has sent a tweet suggesting President Barack Obama is not a "real black president".
In tweets praising Republican candidate Ben Carson, Mr Murdoch wrote: "Ben and Candy Carson terrific. What about a real black President who can properly address the racial divide?"
He also recommended a New York magazine article for "minority community disappointment" with the president.
Mr Murdoch, 84, is founder of the global News Corporation empire.
His company owns Fox News Channel and The New York Post and The Wall Street Journal in the US, and Sky News and The Sun and Times newspapers in the UK, among others.
He is ranked as one of the world's most powerful people.
Mr Murdoch has previously tweeted his admiration for Mr Carson, a 63-year-old retired neurosurgeon who is one of 15 hopefuls vying to become the Republican candidate for the US presidency in 2016.
A few days ago, he tweeted: "Everywhere pundits keep underestimating Ben Carson. But public understand humility as admirable, listen to the multi-faceted strong message."
Previously, he has said of him: "Maybe the one to beat. Irreproachable on background, achievements, character, vision."
He took to Twitter again on Wednesday.
