“I had many fights with Congressional Dems over the years on national security matters,” Brennan tweeted. “But I have never witnessed the type of reckless partisan behavior I am now seeing from Nunes and House Republicans. Absence of moral and ethical leadership in [White House] is fueling this government crisis.” 
Schiff, on Twitter, accused Nunes of violating committee protocol and giving Trump a “secretly altered” version of the memo. 
The FBI took the unusual step Wednesday of publicly voicing “grave concerns” about the memo being released, raising flags about inaccuracies. The memo purports to show surveillance abuses committed by the FBI. 
Brennan served in the CIA under both the Bush and Obama administrations and has defended the FBI against attacks from Trump before.
