If Biden did anything corrupt, he should be investigated.

But you must also take into account that Biden (together with Obama, Clinton, Clapper, Brennan, McCabe, Bush, McCain, etc) are working in US/Western interests when they work with politicians abroad.

This often means working against Russian interests. Many countries (Iran, Israel, SA, Ukraine, now US) have parties & individuals that work with Russian interests against Western interests and vice versa.

RNC has turned 50 years of history on its head. Some are taking money from Russian-Israeli oligarchs. Some have aligned with Russia because they represent Big Oil. Some want to split Russia from China in advance of war with Iran-China.

Biden will be President. Prosecutions will commence and you will see how the RNC has been corrupted by Russian-Israeli mob money and how the Trump family are Russian-Israeli State & mob assets.
