Called "City of Immigrants: A Night of Support," the concert asks attendees to donate to "groups assisting visa holders and refugees," including ACLU of Maryland, National Immigration Law Center, Tahirih Justice Center, and International Rescue Committee.
Tickets are free with a donation to one of these groups, and donations up to $100,000 will be matched by Simon's production company, Blown Deadline Productions.
Simon, screenwriter Beau Willimon, activist and school administrator DeRay Mckesson, author Taylor Branch, and others will give remarks "urging religious and racial inclusivity," Simon's post says.
On Twitter, Simon noted, "I always wanted to get Steve Earle, the finest redneck mensch on the planet, inside a working synagogue."
Now he and many others will get to see it.
