Even Mainstream Media Is Sick And Tired Of Biden's Silence On Trump Crimes

I think Biden is trying to avoid getting entangled in broils that can get

in the way of his ability to pass important bills.  Going on the attack

would not only play into Trump's hands as Trump tries to portray the prosecutions

as politically charged, it would also polarize the Presidency and probably 

prevent Biden from getting any more done while embroiling him in politically

charged battles.  It's a lose-lose situation.
