Donald Sterling hires investigators to dig up NBA dirt

Los Angeles Clippers owner Donald Sterling's team of lawyers has hired four private investigation firms to dig up dirt on the NBA's former and current commissioners and its 29 other owners, a person familiar with Sterling's legal strategy told the Associated Press.

Investigators were given a six-figure budget over the next 30 days to examine the league's finances, allegations of previous discriminatory conduct and compensation to past Commissioner David Stern and current Commissioner Adam Silver.

The person said the investigators also are looking into whether other owners made any off-color jokes, or racist or sexist remarks.
