President Donald Trump repeatedly prodded Ukraine's new leader to work with Rudy Giuliani and the U.S. attorney general to investigate Democratic political rival Joe Biden. That's according to a five-page memo summarizing the July 25 call.
The conversation between Trump and Ukraine's president is just one piece of a whistleblower's complaint made in mid-August.
The complaint is central to the impeachment inquiry announced Tuesday by House Speaker Nancy Pelosi.
Trump told the Ukrainian president "If you can look into it ... it sounds horrible to me." Trump was talking about unsubstantiated allegations that Biden sought to interfere with a Ukrainian prosecutor's investigation of his son, Hunter.
