SACRAMENTO (CBS13) – State Treasurer Bill Lockyer, a fixture in the capital for 40 years, is at the center of an emerging sex scandal between his wife, who’s an Alameda County supervisor, and another man.

The San Francisco Chronicle reports Treasurer Lockyer was sent a sex tape of his wife with the man.

And the treasurer, thinking he was being blackmailed, called the Alameda district attorney to get his wife a stay-away order imposed against the man, identified by the Chronicle as 35-year-old Stephen Chikhani, a construction worker from San Jose.

But the DA’s investigation concluded her relationship with the man was consensual and that no crime occurred.

According to the Chronicle, that affair became public only after Nadia Lockyer called the cops on her boyfriend at a Newark hotel room, accusing him of assault. But no charge was filed in that case either.

Supervisor Lockyer, 40, is now back in rehab, where she first met Chikhani, her political career in question.

Nate Miley is also an Alameda County supervisor, and he doesn’t like the attention his colleague has generated.

“We are very concerned about how the county looks and is perceived,” he said. “We want to go about our business in a professional manner.”

Meanwhile, when asked about concerns over how the treasurer looks or is being perceived in the ordeal, his communications director told CBS13 the career politician is “focused on doing the job he was elected to do.”

Tom Dresslar added there was “no comment other than to say we’re in the middle of a $2 billion dollar bond sale to save the state a boatload of money.”

The fallout between the Lockyers comes after the treasurer bankrolled his wife’s campaign for supervisor with massive amounts of money, a practice political watchdog group Common Cause has tried to end.

“It’s a priority of ours that we can see and track where all our money’s going,” Common Cause’s Phillip Ung said.

From his own election war chest, Lockyer gave his wife $1.5 million dollars for a county race.

“I can’t point to any other instance where that amount of money has been used in a local race,” Ung said.

A Democrat, Bill Lockyer first won a State Assembly seat in 1973. He served 25 years in the legislature and also served two terms as the state attorney general.
