Sen. Ron Johnson (R.-Wis.) told the Wall Street Journal that he learned of a possible quid pro quo between the Trump administration and Ukraine's government from EU Ambassador Gordon Sondland.
The big picture: Johnson said that he pressed President Trump on the issue, which allegedly linked the distribution of $400 million in U.S. military aid with a Ukrainian investigation of former Vice President Joe Biden, in an Aug. 31 phone call. "He said ... 'No way. I would never do that. Who told you that?'" Johnson told the Journal of his conversation with the president.
