O'Malley speaks at 50th anniversary of March on Washington - baltimoresun.com: WASHINGTON -- Gov. Martin O'Malley used a brief speech as part of Wednesday's 50th anniversary of the March on Washington to tie the civil rights movement to a wide range of domestic policy issues, from gun control and immigration to education, gay marriage and the economy.

The Maryland Democrat, who has said he is considering a run for president in 2016, encouraged the thousands assembled on the National Mall to view the event as a call to action for college affordability, an increase in the minimum wage and the protection of an individual's right to vote.

It was among the highest-profile addresses O'Malley has given since he spoke at last year's Democratic National Convention. President Barack Obama will also speak at the event to celebrate the 50th anniversary of Dr. Martin Luther King Jr.'s "I have a Dream" speech.
