4 historic attacks at the U.S. Capitol

Trump supporters breached the U.S. Capitol building in Washington after thousands of people descended on the city to protest against Joe Biden's confirmation certification.

Largely lost from public memory now, the push for nationhood for Puerto Rico and anger at U.S. colonialism spurred attacks on the island and in New York City, all the way up to the Fraunces Tavern bombing in 1975, which killed four people.

The U.S. presence in Vietnam led to a spate of bombings and violent attacks at a host of sites, including U.S. draft board locations as well as corporations, banks and educational institutions seen to be supporting the war effort.

The group said the bombing was in protest of the expansion of the U.S. military presence in Southeast Asia, specifically to Laos.

Given the time of day, no one was injured in the blast, but damage was estimated at $300,000 US. The bombing threatened to derail a peaceful protest planned for Washington in early May and heightened the response from Richard Nixon's administration, events detailed in the recent book by Lawrence Roberts, Mayday 1971: A White House at War, a Revolt in the Streets, and the Untold History of America's Biggest Mass Arrest.
