What Schiff means by “inadequate” is that the Administration didn’t give him key intelligence information about the coming airstrike in Syria because they feared he would either leak it or hold a press conference to warn the Iranians and their Syrian proxies about it so that they could escape.
Schiff is insane and a traitor. At least someone in this crippled administration had the balls to call in the airstrike, even if they gave some kind of warning or waited until most people had left the strike area (to limit casualties, of terrorists - That makes no fu***ing sense. Our job is to kill terrorists, not to let them get away).
Our side should STFU and let our military take out our enemies wherever and whenever we can (usually in cooperation with our allies esp in the Middle East, but the same for hitting Al Shabab in Somalia and Omar in Minneapolis).
In defense of Biden, and it will be a cold day in hell, before that happens, but that is probably exactly why Schiff did not get told. He would told our enemies about it.
