I wouldn't be surprised if Biden impeachment was part of Trump's defense and political strategies.
There's definitely something worth looking into with the Hunter Biden business.
Did Biden use his Office of the Vice President of the United States to enrich family members, friends, and relatives?
Follow the money, the call logs, the text logs, e-mail logs, etc., and find enough evidence to convince the American public.
Since the Patriot Act, it should be more difficult for the Bidens to hide large bank transfers. They probably laundered the money through layered LLC's and Partnerships.
