Here is the exchange:
Johnson: We were misled that there were supposedly protests and then... an assault sprang out of that. And that was easily ascertained that that was not the fact, and the American people could have known that within days -- and they didn't know that.
Clinton (shouting, glaring, and waving her arms): With all due respect, the fact is we had four dead Americans. Was it because of a protest, or was it because of guys out for a walk one night who decided they'd go kill some Americans? What difference -- at this point -- does it make? It is our job to figure out what happened, and do everything we can to prevent it from ever happening again, Senator.
