"I don"t want to be involved to democratic open elections of US state," the Ukrainian president said WASHINGTON: A White House transcript released Wednesday confirmed that President Donald Trump asked his Ukrainian counterpart to probe political rival Joe Biden -- a day after Democrats seized on the explosive allegation to launch an impeachment process. The official memorandum of a July 25 phone call with President Volodymyr Zelensky shows Trump saying US Attorney General Bill Barr and the president"s personal lawyer Rudy Giuliani would be in touch about probing Biden and his son"s activities related to Ukraine. "There"s a lot of talk about Biden"s son, that Biden stopped the prosecution and a lot of people want to find out about that so whatever you can do with the attorney general would be great," Trump said. Democrats, who opened formal impeachment proceedings against the president on Tuesday, are investigating whether he pressured a foreign government to look into a political opponent, and if he used a delayed $400 million aid package as leverage. As Barack Obama"s vice president, Biden and other Western leaders pressured Ukraine to get rid of the country"s top prosecutor, Viktor Shokin, because he was seen as not tough enough on corruption. "Biden went around bragging that he stopped the prosecution so if you can look into it... It sounds horrible to me," Trump told Zelensky in the call.
