Hunter and Joe Biden were involved in their corrupt dealings while Joe Biden was still VP. From 2013 through 2018 Hunter Biden and his company brought in about $11 million via his roles as an attorney and a board member with a Ukrainian firm accused of bribery and his work with a Chinese businessman who was later accused of fraud.
You seriously don't think Hunter Biden the crackhead went to Ukraine on his own, and got a seat on the board of an energy company without having and experience in the energy field, do you?
And if you remember correctly, Joe Biden was also Vice President when he committed quid pro quo by threatening to withhold that billion dollars to Ukraine.
