The Washington Convention Center is a sea of purple and gold this weekend as the Omega Psi Phi fraternity celebrates its 100-year anniversary.
The fraternity was founded at Howard University in 1911. Its members range from Michael Jordan to Tom Joyner to Jesse Jackson, who recites their motto, "Manhood, scholarship, a will to persevere and lift up others."
"The Omegas are often known as the fraternity that like to have lots of fun, although some people don't like that," D.C. attorney and Omega member Fred Cooke said. "Barking is officially frowned on. We don't do that; we are Omega men, we're not dogs."
In the black fraternity world, they are considered amongst the wildest. Some burn their Omega symbol into their skin with branding irons.
For many it's generational, say the Burkes, father and son and uncles from Tennessee state. They came from coast-to-coast, posing, but also performing community service.
"Clean up the streets, we feed the homeless help out as much as possible," said Florida A&M member Garrett Solomon.
They're here all weekend. The U.S. Attorney for D.C., Ron Machen, is also an Omega. We hear he warned his fraternity brothers to behave.
