WATCH: Trump Brags About His MSG Rally Being Compared to 1930s Nazi Gathering

Madison Square Garden normally hosts sporting events and concerts, with a very brief history of political rallies held there during its history. A former site of the Democratic National Conventions in 1924, 1976, 1980, and 1992, it also welcomed the Republican National Convention in 2004.  

Former presidents John F. Kennedy, Franklin Delano Roosevelt, and Richard Nixon held events in MSG; FDR and Nixon's events were campaign rallies. Pope Francis held a mass in MSG in front of a capacity crowd in 2015, and Pope St. John Paul II also held a rally in the arena in 1979. 

But it was one specific rally in 1938 that's at the forefront of everyone's mind thanks to Donald Trump holding his own version of a Nazi rally at MSG on Sunday.

And Trump is fine with that, regardless of what he says.

The lineup for Sunday's rally is a Who's Who of "Who's That?" poised for an attack on America in the heart of New York City. 

The New York Times, which has had a spotty history of holding Trump accountable, pulled no punches with its Sunday coverage.

While the MAGA cult swarmed around MSG to get in early--because THE TICKETS WERE FREE--Twitter users reminded anyone bragging about the event that plenty of liberals also signed up for tickets with no intention of using them.

Counter protestors were assembling outside the Garden hours before the event began to shout down the MAGA cult crowd, including A Veterans Against Trump rally scheduled just outside the arena.
