Still, when Joe Biden went to Ukraine, he was not trying to protect his son — quite the reverse.
The then-vice president issued his demands for greater anti-corruption measures by the Ukrainian government despite the possibility that those demands would actually increase – not lessen — the chances that Hunter Biden and Burisma would face legal trouble in Ukraine.

Giuliani, Trump, and their lackeys began spreading the false accusation that Biden had traveled to Ukraine to blackmail the government and force officials to fire the country’s chief prosecutor, Viktor Shokin, to derail an investigation into Burisma.

Shokin had been forced from office at Biden’s urging because he had failed to thoroughly investigate corruption and stifled efforts to expose embezzlement and misconduct by public officials. Biden did threaten to withhold $1 billion in U.S. loan guarantees unless Shokin was ousted. But that was because Shokin had blocked serious anti-corruption investigations, not because he was investigating Burisma.
