Rudy Giuliani met with disgraced Ukrainian prosecutor Yuri Lutsenko in January 2018. And during the meeting, Giuliani called President Trump to patch him in.

This is a third-hand story given by the former United States Ambassador to Ukraine Marie Yovanovitch. She did not claim to have seen this happen, only that one of her aides had been told this by a Ukrainian deputy prosecutor named Yevhen Yenin.
