FILE - In this Monday, Aug. 22, 2011 file photo, the statue of Dr. Martin Luther King, Jr. is seen unveiled from scaffolding during the soft opening of the Martin Luther King, Jr. Memorial in Washington. The dedication of the Martin Luther King Jr. Memorial on the National Mall in Washington has been postponed indefinitely as Hurricane Irene bears down on the East Coast.

WASHINGTON — Members of the Alpha Phi Alpha fraternity had worked for more than a quarter-century to get a monument on the National Mall honoring Martin Luther King Jr., one of their own.

So even though the approach of Hurricane Irene led organizers to postpone Sunday's official dedication, the fraternity went ahead with its own ceremony Friday at the memorial site.

Martin Luther King III accepted the 30-foot tall monument honoring his father. Fraternity brothers dressed in black suits or gold jackets marched quietly to the memorial.
