(CNN) The latest batch of text messages provided to Congress on Thursday between two top FBI employees who have come under scrutiny for criticizing then-presidential candidate Donald Trump capture their immediate reactions to the firing of FBI Director James Comey and the appointment of special counsel Robert Mueller.
