Former Secretary of State Colin Powell announced Tuesday that he will be voting for Democrat Hillary Clinton.

Powell, a retired four-star general who served at Clinton's former post under George W. Bush, made the disclosure at a meeting of businessmen in New York, according to the Associated Press.

The 79-year-old statesman has called fellow Republican Donald Trump a "national disgrace", and condemned him for his role in the 'birther' movement, saying he "takes [African-Americans] for idiots."

"He is at one percent with black voters, and will drop...he can never overcome what he tried to do to Obama."

Powell has also criticized Clinton, in a leaked email regarding her private server scandal, when she appeared to legitimize her use of a private server by claiming Powell apparently advised her on the issue.

"I have told Hillary's minions repeatedly that they are making a mistake trying to drag me in, yet they still try," he wrote to former advisor to President Bill Clinton, Vernon Jordan, according to the Washington Post.

Powell is not the first statesman tied to the Bush administration to reject Donald Trump's candidacy.

Former New Jersey Gov. Christie Whitman, who was EPA administrator under Bush, has endorsed Clinton, while Barbara Bush and Jeb Bush have disavowed Trump in comments both made earlier this year.

Both presidents Bush have not made official public comments or commitments about the candidate they will choose.
