The "Justice for 6" rally drew a lower-than-expected number of demonstrators Saturday outside the fenced-off Capitol.

An estimated 1,000 demonstrators were expected for the event. But the event drew about 400 people, a low number given the media attention generated in the days leading up to Saturday.

The Associated Press noted that media and U.S. Capitol Police and Washington, D.C.'s police department "vastly outnumbered the demonstrators in attendance."

Four people were arrested. One person was in possession of a gun, one had a knife and two had outstanding warrants in Texas, according to Capitol Police.

The rally was organized by the nonprofit, "Look Ahead America" and led by former Donald Trump campaign aid Matt Braynard. On its official website, the group says it is "standing up for patriotic Americans who have been forgotten by our government."

The rally was in reference to the Jan. 6 riot on the Capitol by a mob of Trump supporters who sought to overturn the 2020 election by disrupting Congress who were assembled to formalize Joe Biden's victory.

NBC News reported Wednesday that right-wing social media tried to steer people away from the rally because it would lead to conflict with the FBI.

According to reports, there were hundreds of police officers were at Saturday's rally. There was also a metal fence around the Capitol.

Rolling Stone reporter Peter Wade that the "rally for supporters of the 'Big Lie' is looking like a big flop."
