Protests sponsored by A.N.S.W.E.R. were held in Washington, D.C., San Francisco, and Los Angeles to demonstrate against the Iraq War three days after the fall of Baghdad. In Washington, the march route took the group of 30,000 past offices of several mass media organizations, and companies such as Bechtel and Halliburton.[54][55]

The Washington DC rally attracted 20,000 (BBC estimate) protesters. The protest ended with a rally at the Washington Monument, within sight of the White House. As well as opposing the invasion of Iraq protesters also called for the repeal of the USA PATRIOT Act.

A pro-war demonstration in Washington organized by Free Republic attracted only dozens (BBC estimate) of people.

As part of the 2004 Republican National Convention protests, United for Peace and Justice organized a mass march, one of the largest in U.S. history, in which protesters marched past Madison Square Garden, the site of the convention. The march included hundreds of separate contingents as well as individual marchers. The group One Thousand Coffins held a procession of one thousand full-scale flag-draped cardboard coffins, commemorating each of the U.S. fallen troops as of that date, carried by a nationwide coalition of citizens, veterans, clergy and families of the fallen. Several hundred members of Billionaires for Bush held a mock countermarch. Estimates of crowd size ranged from 120,000 (unnamed police spokesman) to over 500,000 (organizers, second unnamed police source).[58] In March, 2007 NYPD Deputy Commissioner Paul Browne stated about the RNC protests: "You certainly had 800,000 on August 29th."[59]
