U.S. Republican presidential candidate Donald Trump's campaign aides in 2012 reportedly fought the release of Ukrainian political leader Yulia Tymoshenko when she was in jail.The Associated Press reports that a consulting firm run by former Trump campaign chairman Paul Manafort and his deputy Rick Gates was working for Ukraine's Party of Regions and directed a multimillion-dollar lobbying effort between 2012 and 2014 that undercut U.S. public support for Tymoshenko, though she was considered a political prisoner by the United States and European governments at the time.
