Sure you would have, Mr. Schiff

At least Adam Schiff no longer is (as so many still are) arguing that the Horowitz report isn't a scathing rebuke of the FBI's FISA abuses.  He is, however, asserting to fellow-traveler Chris Wallace that he's shocked, shocked to discover the abuses at this late date:

“I’m certainly willing to admit the inspector general found serious abuses of FISA that I was unaware of,” he said to host Chris Wallace. “Had I known of them, Chris, yes I would have called out the FBI at the same time.“

Not that I take this protestation of retroactive good faith at face value, but it does lay the ground for serious difficulty as soon as someone can establish that obviously he was on notice of the FISA abuses two years ago.  Schiff's reputation for honesty being roughly on a par with his reputation for painstaking avoidance of leaving an incriminating paper trail ("I never met with the whistleblower and don't even know who he is!"), this shouldn't even pose a minor hurdle for the sleuths.
