ABC News reported on Friday that Michael Flynn, the former White House national security advisor, would testify that he was directed to make contact with Russians during the presidential campaign in 2016. Flynn pleaded guilty to lying to the FBI about his post-election contacts with Russia's ambassador to the U.S.

The ABC report was later corrected the story to say its source had clarified that Trump gave Flynn the directive "shortly after the election" to discuss strategies for fighting the Islamic State extremist group.

Last week, gold prices ended higher and the dollar weaker on Friday after Flynn pleaded to lying to the Federal Bureau of Investigation about his communications with the Russian ambassador to the U.S. in December 2016. He also admitted to speaking with a top member of the Trump transition team regarding his communications with the Russian ambassador.
