It's true that Joe Biden leveraged $1 billion in aid to persuade Ukraine to oust its top prosecutor, Viktor Shokin, in March 2016. But it wasn't because Shokin was investigating Burisma. It was because Shokin wasn't pursuing corruption among the country's politicians.
As European and American diplomats pressed Ukraine to clean up its corruption, they focused on Shokin's leadership of the Prosecutor General's Office, which he took over in February 2015.
Despite a Senate GOP investigation that found no wrongdoing by Joe Biden on foreign policy in Ukraine, claims to the contrary continue to circulate.
