Esper says “exquisite” intelligence of a kind only shared with Gang of 8, top leaders in Congress, involved in Soleimani strike. This is more descriptive than Pompeo’s remarks earlier but still short on details.
"Exquisite" is an intel term, implying info obtained from a sophisticated (often technically so) source or platform. Soleimani's communications might be a safe guess. That Esper chose this word suggests he wants to attach some special significance to the intel. We shall see.
