OLYMPIA, Wash. (AP) — State officials say a former GOP Washington state senator and a Donald Trump appointee is responsible for a mailer last week criticizing Democratic lawmakers for a proposed change to the estate tax. The Seattle Times reports according to the state Public Disclosure Commission Don Benton was named as in a commission investigation into complaints alleging the mailer lacked disclosure information. The campaign-style mailer claimed the bill would impose a 40% estate tax for people and small businesses. The bill would raise the threshold of the existing estate tax, meaning fewer people would pay it, and expand the tax at the higher end, meaning wealthier people would pay more.
