Morello was born on May 30, 1964, in Harlem, New York, to Ngethe Njoroge and Mary Morello. Morello, an only child, is the son of an American mother of Italian and Irish descent and a Kikuyu Kenyan father. His mother was a schoolteacher from Marseilles, Illinois, who earned a Master of Arts at Loyola University, Chicago and traveled to Germany, Spain, Japan, and Kenya as an English language teacher between 1977 and 1983. His father participated in the Mau Mau Uprising and was Kenya's first ambassador to the United Nations.
Axis of Justice
Morello and Serj Tankian of System of a Down are the co-founders of Axis of Justice, a political group whose declared purpose is "to bring together musicians, fans of music, and grassroots political organizations to fight for social justice together." They "aim to build a bridge between fans of music around the world and local political organizations to effectively organize around issues of peace, human rights, and economic justice." The group has worked for such causes as immigrant rights and death-penalty abolition. Its recommended book list includes such authors as Karl Marx, Che Guevara, George Orwell, Noam Chomsky, Mumia Abu-Jamal and Grant Morrison.  Morello and Tankian, together with a handful of other artists, including Maynard James Keenan, Wayne Kramer of the MC5, the hip hop group Jurassic 5, and Michael "Flea" Balzary of the Red Hot Chili Peppers, released a live recording of covers and original songs, titled The Axis of Justice Concert Series Volume 1.  On April 6, 2006, Morello was honored with the Eleanor Roosevelt Human Rights Award for his support of worker's rights and for his AOJ work. Morello has worked on numerous labor campaigns: the Guess sweatshop boycott, the LA janitors strike, the Taco Bell boycott, the southern California grocery workers strike and lockout, and others.  Morello was a strong supporter of the 2006 United States immigration reform protests around the US. He feels that there's enough room for everyone in the United States. Morello played as the Nightwatchman at MacArthur Park in Los Angeles and has featured many articles on AOJ. On September 28, 2006, Morello was one of 400 protesters arrested protesting in support of immigrant hotel workers' rights, in what organizers called "the largest act of civil disobedience in the history of Los Angeles". Morello knew he was going to be arrested; he wore bright yellow signs, and gave the LAPD his driver's license number a few days before the march. Morello told MTV:  "In these political dark ages, it's important for us to stand up for one another. These hotel workers by the airport make 20% less wages than the hotel workers around the rest of Los Angeles. We are here to express our solidarity with them, to help them unionize and help them close the gap between their sub-poverty wages and the millions and millions of dollars the people who own these hotels make."
