What will help it go away is the fact that the left could care less what the Bidens did. The only thing that matters is defeating Trump, regardless of how dirty and/or incompetent their candidate is. Also, the govt. bureaucracy will protect its own and its dirty money sources, adding to the impetus to make it go away. Remember, the vast majority of the government is democrat/socialist/leftist, where credentials and legality don’t matter that much.
And a good portion of the Joint Chiefs and flag officers are as well.
