We might want to ask Giuliani about this. As a matter of fact, why hasn’t Giuliani been arrested yet? He has broken several laws including the Logan Act:
When Republican lawmakers this week abruptly canceled a plan to subpoena a former Ukrainian official in their investigations into the energy firm that hired former Vice President Joe Biden’s son, they said it was to allow more time for senators to receive additional briefings.
But a Ukrainian magazine editor has told CNN that the target of the subpoena, Andrii Telizhenko, once offered him money to lobby US senators on behalf of pro-Russian media outlets.
A former Ukrainian diplomat, Telizhenko is an ally of Trump’s personal lawyer, Rudy Giuliani, and has been an enthusiastic proponent of the debunked theory that Ukraine, and not Russia, interfered in the 2016 US elections. Telizhenko has also backed Republican claims that Trump’s Democratic rival, Joe Biden, shut down an investigation into the Ukrainian gas company Burisma when his son, Hunter, served on its board. Biden has consistently denied any wrongdoing.
