(CNN) Former FBI Director James Comey on Friday skewered the Republican memo that alleges the FBI abused its surveillance authority.

"That's it? Dishonest and misleading memo wrecked the House intel committee, destroyed trust with Intelligence Community, damaged relationship with FISA court, and inexcusably exposed classified investigation of an American citizen. For what?," Comey wrote on Twitter Friday.

He added, "DOJ & FBI must keep doing their jobs."
