A key witness in the trial of Roger Stone on Thursday described the breakdown in their unlikely relationship that culminated in special counsel
Robert Mueller filing charges against Stone.
Randy Credico's interactions with Stone are at the heart of the case against the longtime confidant of President Donald Trump.
Stone is accused of lying to
Congress to conceal his efforts to contact
WikiLeaks for information on the Russian-hacked
Democratic National Committee emails and then tampering with a witness —Credico — by trying to prevent him from contradicting Stone's testimony.
