So let me get this straight, White House personnel are refusing to testify to clear themselves of crimes they are accused of? Surely if they are innocent and have proof of that they can not only testify and clear their names but also in doing so reinforce the 'witch hunt' narrative in the public eyes. If they were innocent this would be an incredible opportunity to bury the Democrats. The republicans aren't known for passing up these opportunities. If I was accused of murder I'd damn sure want to clear my name.
