Anti-war speakers included Charley Richardson and Nancy Lessen from Military Families Speak Out and Liz McAlister, partner and widow of the late peace activist Philip Berrigan. “No blood for oil!” demanded disabled Vietnam War veteran Ron Kovic, author of “Born on the Fourth of July.”

Communist organized healthcare rally
In October 2009, Several hundred community and labor activists rallied at the historic Senator Theater, Baltimore, demanding that Congress pass heath care reform that includes a public option.
The event was chaired by City Councilman Bill Henry.
In her remarks, event organizer, Communist Party USA member Caroli Mullen targeted "moderate" Congress people who were sitting on the fence, telling the audience that "Democrats better get some spine,"
According to Mullen, reform must be based on the premise that health care is a right, not a privilege.
Mullen said that while she supports a public option, a single-payer system was the best way to provide comprehensive, universal care.
The AFL-CIO's Mason pointed out that union workers often gave up wage and pension increases to save their health care coverage.
Mason called for a plan that covers the 47 million uninsured without punishing insured workers "who have already given and given."

"Happy birthday Fidel"
The Baltimore branch of Workers World Party celebrated the 90th birthday of Cuba’s historic leader, Fidel Castro, on Aug. 13, 2016. An introductory panel featured Fred Mason, president of the Maryland/Washington, D.C., AFL-CIO; Leslie Salgado, from Howard County Friends of Latin America; and Cheryl LaBash, a co-chair of the National Network on Cuba. In a “fish bowl” discussion, four young organizers described what socialism means to them, followed by questions and comments from others.
Sharon Black, an independent candidate for City Council president, chaired the meeting, and Andre Powell, mayoral candidate — both from Workers World Party and the Baltimore People’s Power Assembly — spoke in solidarity with the Cuban revolution. Independent City Council candidate Nnamdi Lumumba, of the Ujima People’s Progress Party, also expressed his solidarity with socialist Cuba.
