Thousands were tweeting Friday afternoon about the curious timing of Gen. David Petraeus's resignation as head of the CIA. 

Petraeus was mentioned more than 57,000 times between 3 and 5 p.m.  ET Friday after his announcement, according to data from Topsy Pro. And housands of those tweets suggested the timing has something to do with Benghazi and his scheduled testimony on Capitol Hill next week. Here's what some conservatives and journalists had to say: 

“This had nothing to do with Benghazi or relationship with the White House — which by the way was excellent — or anything else for that matter,” a former aide told Wired's Danger Room.  “Just his flawed behavior.”
