It seems like Colin Powell - the US Secretary of State during former President George W. Bush's administration, is keen on supporting neither Donald Trump nor Hillary Clinton for the presidency if his personal emails are to be believed.

Hackers managed to gain access to Powell's personal emails, which contain scathing remarks against both Trump and Clinton. The former four-star general ripped the Republican Party nominee apart, calling him a "national disgrace" and "international pariah," The Washington Post reported.

"Yup, the whole birther movement was racist. That's what the 99% believe. When Trump couldn't keep that up he said he also wanted to see if the certificate noted that he was a Muslim," said Powell in one of his emails accusing the real estate mogul of being a birther in an NPR report.

Powell's email to Emily Miller - his deputy press secretary at the State Department, sent on June 17, 2016 criticized Trump for being "in the process of destroying himself, no need for the [Democrats] to attack him" and called him a birther. The stolen emails have been given to DCLeaks.com.

USA Today said that members of the Democratic Party as well as computer experts admitted that DCLeaks.com may be connected with intelligence forces from Russia. Concerns that the website may be intended to sway the results of the US presidential election have also been floated.

Clinton wasn't spared from Powell's attacks. In another email sent back in March 9, 2015, Powell told the Clinton camp that "they are making a mistake trying to drag me in, yet they still try. The media isn't fooled and she is getting crucified."

Another set of emails dated May 2016 show that Powell criticized Clinton for citing his private email account usage to justify her use of a private email server when she was Secretary of State. He added in an August 18, 2016 email that "everything [Clinton] touches, she kind of screws up with hubris."

Another email sent in August 2016 to NBC News reporter Andrea Mitchell said that Powell "told [Clinton] how I was using my personal computer for [unclassified] emails. I said nothing about servers, basements, domains, Clinton foundation, government employees..."

Powell didn't confirm whether the leaked emails were authentic. "I wasn't aware of any infiltration of my Gmail account...If accurate my privacy has been violated," said the retired statesman in an interview with The Daily Caller.
