The FBI warned Hillary Clinton's campaign that it was the target of a cyberattack five months ago, but was spurned in its attempt to investigate,
Yahoo News reported.
The Bureau back in March detailed for the Clinton campaign how it was being targeted and requested logs and contact info to investigate, but was turned away, Yahoo News reported.
The Clinton campaign thought the request for sensitive material was too intrusive, the Yahoo report said, especially given the ongoing investigation into Hillary's private email server.
Yahoo reported the FBI assured Clinton's campaign that the investigations would be separate, but that the campaign was too skeptical to turn over the information to the Bureau.
Weeks later, the Democratic National Committee discovered it had been hacked, according to Yahoo.
