A Republican donor who died soon after telling a newspaper he tried to obtain Hillary Clinton's emails from Russian hackers during the 2016 presidential election killed himself, according to a report.
Peter W Smith, a former equity adviser, was found dead around ten days after telling the Wall Street Journal he tried to acquire emails missing from Ms Clinton's server.
Ms Clinton said she deleted some 30,000 online messages because they related to her personal life.
But Mr Smith told the Journal he thought the emails were connected to her official duties. He said and his team had found five groups of hackers, two of them Russian, who claimed to hold the emails.
Mr Smith claimed his efforts were independent of Donald Trump's campaign. Yet he implied he was working with Lt Gen Michael Flynn, who served as the President's national security adviser until he was fired over his alleged contact with Russian officials.
A cache of emails from the Democratic National Committee were published online during the election campaign. US Intelligence agencies said Russia launched a cyber attack in July last year with the intent of helping Mr Trump's campaign.

According to death records from Olmsted County, Minnesota, Mr Smith killed himself in a hotel near the Mayo Clinic on 14 May, The Chicago Tribune reported.
Police found a note from the 81-year-old saying he was taking his own life because of bad health and an expiring life insurance policy, the newspaper said.
In the note recovered by police, Smith reportedly apologised to authorities and said "NO FOUL PLAY WHATSOEVER" was involved in his death.
He reportedly said he he was taking his own life because of a "RECENT BAD TURN IN HEALTH SINCE JANUARY, 2017", adding that the timing related to life insurance of $5 million expiring.
Earlier this week two Democratic Party donors and a former party staff member launched an invasion of privacy lawsuit against Mr Trump's campaign and one of the President's advisers,
They are accusing them of conspiring in the release of hacked Democratic emails.
