Several tributes will take place today in our region to mark the 12th anniversary of the 9/11 attacks.
One of those is bringing thousands of bikers to the area.
A motorcycle rally, known as Two Million Bikers, will ride along the National Mall.
The event doesn't come without controversy however.
Riders are holding it despite not having a permit from the National Park Service to do so.
The group has also received criticism for having a strong anti-Muslim stance.
The group says they just want to honor the victims of 9/11 and military members.
