A union leader claims to be the target of a smear campaign. Dave Regan alleges that wealthy individuals are behind the effort, which he believes is motivated by their opposition to a billionaire tax measure he supports.

The billionaire tax measure was championed by Regan, who now says he is a victim of a campaign intended to damage his reputation.

Further details about the alleged smear campaign are available from the source, including the role of wealthy Californians who oppose the tax measure.
