Sports briefs: Seattle billionaire fights Sacramento arena plan

NBA • Seattle billionaire Chris Hansen, who tried to move the Kings NBA franchise from Sacramento, is behind a secretive effort to thwart the city's efforts to build a new downtown arena for the professional basketball team, California's campaign watchdog disclosed Friday after an investigation.

The announcement is an embarrassment for Hansen, who lost his bid after NBA owners voted to keep the team in California's capital city, and could undermine support for the local ballot measure Hansen funded that is designed to put to a citywide vote the council's planned $258 million subsidy for a downtown arena.

Hansen publicly wished the city well after losing his bid to buy the team. Yet the California Fair Political Practices Commission said that just a month later Hansen gave $80,000 to pay signature gatherers trying to get the measure on next June's ballot, and the group violated state law by refusing to disclose the donation.
