Especially if he (wink wink) knew there was a warrant to wiretap the Russians, who just happened to talk to some of Trump’s associates (Kelly, Manafort, etc), then he can say what he did without lying. Clapper and also deny it as he did without lying and Comey can ask DOJ to deny it as he did.
No one is lying but no one is telling the complete truth either.
Too clever by half?
Maybe the answers to some very pointed and direct questions might be telling. No wiggle room for parsing and spinning. The correctly worded question might reveal the truth (or result in another lie that can be checked on).
