SACRAMENTO, Calif. — A California couple has claimed a $528.8 million share of a record Powerball jackpot from January and pledged to give much of it to charity.

Flanked by security, Marvin and Mae Acosta went to a state lottery office in Van Nuys on Friday to claim their winnings from the record $1.6 billion Powerball drawing, lottery officials disclosed Tuesday.

In a statement, the Acostas said they are dedicating nearly all of the prize money to a trust and charities.
