OLYMPIA, Wash. (AP) — Lawmakers introduced on Wednesday a measure that would gradually lower liquor sales taxes from 20.5 percent to 6.5 percent over eight years.

The measure, which is backed by Republican and Democratic lawmakers, is in response to Washingtonians crossing borders to buy cheaper booze in Idaho and Oregon. Last month Idaho regulators reported that Washingtonians boosted the Gem State’s coffers by $10 million.
