He can do it as long as he wants. He is completely immune. He refuses to allow legal oversight by Congress. Yesterday he was bragging about all the "reforms" he implemented yet refuses to release the descriptions of those reforms to Congress. So, when the FBeeI colluded with the Clowns to bring a US citizen to Europe to entrap a member of Trump's team, Wray pleads ignorance, but assures us it won't happen again (Crossfire Hurricane). Right....
Thank you! Bang on! Wray believes that he and the DS cabal now run the country! Congress answers to him! The Constitution is dead (according to Wray!)
