Robert Mueller never found any evidence that Trump campaign adviser George Papadopoulos told anyone on the campaign that he was tipped off about the Russians having emails that could damage Hillary Clinton.
Papadopoulos was told in April 2016 by a Kremlin-linked professor that the Russians had thousands of emails that were damaging to Clinton, according to court filings. That wasn’t publicly known at the time. It wasn’t until months later, when WikiLeaks and other Russian-backed websites, started releasing tens of thousands of embarrassing emails stolen from the Democratic National Committee.
"When interviewed, Papadopoulos and the campaign officials who interacted with him told the (special counsel’s) office that they could not recall Papadopoulos's sharing the information that Russia had obtained 'dirt' on candidate Clinton in the form of emails or that Russia could assist the campaign through the anonymous release of information about Clinton," the report said.
The report continued: "No documentary evidence, and nothing in the email accounts or other communications facilities reviewed by the office, shows that Papadopoulos shared this information with the campaign."
