Longtime Trump adviser Roger Stone bragged about Wikileaks' plans to release stolen emails from Democratic Party officials on conference calls during the run-up to the 2016 election, the Wall Street Journal reports.

At least twice during August 2016, the Trump adviser had conference calls where he told callers about WikiLeaks’ plans to release information that he said would affect the 2016 presidential campaign before the election, the paper reports.

The report is sourced to "people who listened to the sessions and recordings of one of the calls published online and reviewed by The Wall Street Journal."

It's a matter that special counsel Robert Mueller’s investigators are looking into, "according to a witness in the probe and another person familiar with the matter."

“In the background of this entire race going forward is the fact that Julian going to continue to drop information on the American voters that is going to roil this race,” Mr. Stone said on Aug. 4, 2016. “He has made that very clear.”
