The testimony was held behind closed doors, but the two sources say Volker "said he tried to caution Guiliani that his sources, including Ukraine's former top prosecutor, were unreliable," per the Post. Volker also reportedly said he told Ukrainians to stay out of U.S. politics.

ABC News also reports that Volker shared text messages with Congress to other top American diplomats, which read "I think it's crazy to withhold security assistance for help with a political campaign."
