Lantos, 79, a California Democrat and chairman of the House of Representatives' Foreign Affairs Committee since the beginning of 2007, is known for his dedication to human rights issues. He is serving his 14th term as a House member. Lantos' Bay area-based 12th district leans strongly Democratic, though he has faced primary challenges in the past from the left.
"It is only in the United States that a penniless survivor of the Holocaust and a fighter in the anti-Nazi underground could have received an education, raised a family, and had the privilege of serving the last three decades of his life as a member of Congress," Lantos, who was born in Budapest, Hungary, said in a statement. "I will never be able to express fully my profoundly felt gratitude to this great country."
In 1944, as a teenager, he was sent to a labor camp but eventually escaped.
