Trump just fired Jeff Sessions as Attorney General and replaced him with Matthew Whitaker. If you don’t know Matthew Whitaker, he’s a political hack who has spoken in great detail about ways to hurt the Mueller investigation.
It’s pretty obvious why Trump chose Whitaker. The Blue Wave flipped the House of Representatives into Democratic control, and Mueller is getting closer to the truth about Trump’s crimes and corruption. So he essentially replaced Mueller’s old boss (Deputy Attorney General Rod Rosenstein) with a new boss that has no problem intervening and obstructing justice. You can learn more here.
This is a red line, and Trump just crossed it. Now it’s time to act. Tell your Member of Congress to publicly call for Matthew Whitaker to recuse himself from overseeing the Mueller investigation.
