Dennis Richardson, Oregon secretary of state and former candidate for governor, died at his Central Point home Tuesday night, his office announced Wednesday. He has been fighting brain cancer for months.

"Dennis passed away at his home surrounded by family and friends," according to a statement from Leslie Cummings, deputy secretary of state.

"If you spent time with Dennis, it wouldn’t be long before he shared with you his personal motto of “Pro Tanto Quid Retribuamus,” which means: Having been given much, what will you give in return? This philosophy influenced every aspect of Dennis’ life and became the hallmark by which many knew him," her statement said.
