Calls for Trump Impeachment Grow After Trump Ukraine Leader Conversation VOA News VOA Ukrainian service reporter Myroslava Gongadze contributed to this report Democratic lawmakers are considering formally launching an impeachment investigation into President Donald Trump Tuesday, following news reports that he froze Congressionally-approved funding for Ukraine while pushing the country to investigate one of his political rivals. Facing mounting pressure, the president pledged Wednesday to release the "complete, fully declassified and unredacted" transcript of his phone call with Ukraine's leader that is at the center of a debate between Congress and the White House over a whistleblower complaint. News reports had said Trump pressured Ukraine's president to investigate leading Democratic presidential candidate Joe Biden and his son, Hunter, who served for years on the board of a Ukrainian gas company. "You will see it was a very friendly and totally appropriate call. No pressure and, unlike (former Vice President) Joe Biden and his son, NO quid pro quo! This is nothing more than a continuation of the Greatest and most Destructive Witch Hunt of all time!," Trump said on Twitter Tuesday.

"As far as withholding funds, those funds were paid," Trump said. "But my complaint has always been, and I'd withhold again and I'll continue to withhold until such time as Europe and other nations contribute to Ukraine." Trump has insisted he did nothing wrong during the phone call but also acknowledged, "there was pressure put on with respect to Joe Biden. What Joe Biden did for his son, that's something they should be looking at."
