Why Did Pelosi Call AG Barr a Criminal?

Talk about the kettle calling the pot black! Nancy is calling Attorney General Barr a criminal! Pelosi is following the edict of "Rules for Radicals" trained Hillary Clinton, in which she says "call your enemy out by accusing them of breaking the same laws that you are breaking". Why is Barr a criminal, according to Pelosi? Or, is it that Pelosi is the real criminal?
