As the special counsel continues to follow the facts and is circling President Trump’s longtime fixer Roger Stone, one name has emerged as pivotal in Mueller’s investigation into whether any Americans conspired with the Kremlin: Jerome Corsi.

Corsi has known President Trump for decades dating back to the 1980s when Trump and Corsi were business associates, and has been tied to Roger Stone for years. According to ABC News, Corsi has met with Robert Mueller’s team several times over the last week, and is scheduled to make a second appearance in front of the grand jury for the Russia investigation.

Reports indicate Corsi may have communicated with WikiLeaks about the Russian theft of Clinton campaign emails, and could have been the pass-through between Russian intelligence officers and the Trump campaign.
