As noted, congressmen “would like to know what data Jovanovic has about the transactions” of presidential lawyer Rudolf Giuliani in Ukraine and on whose instructions he arrived in this country to “find dirt on ex-vice president Joe Biden.”

Earlier, Rudolph Giuliani said that he did not carry out a political assignment in Ukraine regarding incriminating evidence on Joe Biden.

At the same time, a special committee of the US House of Representatives published an intelligence complaint against Trump because of a conversation with Ukrainian President Vladimir Zelensky.

The author of the complaint, citing “numerous officials”, notes that the president “uses his powers to get another country to intervene in the 2020 US elections,” including “to conduct an investigation against one of the president’s main political rivals.”

The central figure in these efforts is the personal lawyer of the head of state, Rudolf Giuliani, the author of the document noted.
