HARRISBURG, Pa. (AP) — With challenges mounting to the proposed privatization of the Pennsylvania Lottery’s management, Gov. Tom Corbett’s administration is trying to counter negative publicity and make the case that a British firm’s $34 billion bid is the best option to satisfy growing demand for state services for the elderly.

The firm, Camelot Global Services, which runs the official lottery in the United Kingdom, has submitted the sole bid to manage the $3.5 billion lottery system, pledging at least $34 billion in profits over 20 years.
