This week, lifelong animal activist and television star Bob Barker announced he would match all donations made to People for the Ethical Treatment of Animals (PETA) during its current challenge to raise $250,000 by July 4. Online donors can choose between donating in increments of $25, $50, and $100, with an option to also submit a customized amount. Barker is a longtime PETA supporter, and often gifts large donations to animal organizations. In March, Barker donated $2.5 million to help PETA build new offices in Los Angeles, Calif. The retired The Price is Right host attended the ribbon cutting at the Bob Barker Building on Sunset Boulevard, where PETA President Ingrid Newkirk praised his generous donation.
