Rudy Giuliani, former Sen. Joe Lieberman, and a slate of other prominent U.S. figures joined thousands of dissidents at a virtual summit calling for regime change in Iran.

The Friday event marked the annual gathering of the National Council of Resistance of Iran, a leading opposition group that works to topple the government of Iran. Usually, the gatherings are held in Europe and bring together dozens of speakers and thousands of attendees, but this year, because of the coronavirus pandemic, it was held online through the popular communication platform Zoom.
