The DC rallies seem to get the most press attention, yet the NYC rally on July 22nd had by far the most people.
You can still see the last NYC rally which had 24 speakers and lasted 3 hours in its entirety here:

The only speakers to do both NYC rallies are James Woolsey and Kevin McCullough. Rest of today’s speakers are new.
There’s already been several Stop Iran Rallies held across America and in Toronto as well.
