"I have made a decision. And my decision is, I'm going to run for president of the United States," Hutchinson said in an interview with a US broadcaster.
The former governor said Trump should withdraw from the presidential race in view of his indictment.
"I don't believe he should be the next leader of our country," Hutchinson added.
On Thursday, the Manhattan Grand Jury voted to indict Trump on charges related to his alleged role in a hush money payment and cover-up involving adult film star Stormy Daniels during the lead-up to the 2016 election. Trump denies the allegations, as well as the affair, and has characterized the case as a "witch hunt" and political persecution.
