Grijalva, the son of a Mexican immigrant who rose to the halls of Congress in a public-service career that stretched more than 40 years, has died.

Rep. Grijalva died Thursday of complications from cancer treatment, his office said in a statement. He was 77.

Colleagues and friends of Raúl M. Grijalva are remembering the 12-term congressman from Arizona for his tireless efforts to protect the environment, advance tribal interests and fight for equality.
