I think Mueller is going to indict all of those present at the Trump Tower meeting of June 9th

44. There is so much we do not know

The fact that Trump and his associates had been surveilled by foreign intelligence agencies and audio tapes exist is enough to convince me to let this play out in its entirety before casting any judgment as to who may or may not be ensnared in the gargantuan web. Everything we know, we know because someone leaked it to the press. The powers that be want the public to keep their eyes on the prize. Eventually, we'll see the full picture. Right now, we're still largely operating in the dark.
