Listen • 1:17 Miles of unused pipe, prepared for the proposed Keystone XL pipeline, sit in a lot outside Gascoyne, N.D., in 2014. Fourteen Republican attorneys general, including Montana’s, are protesting Pres. Joe Biden’s decision to cancel a border crossing permit vital to construction of the Keystone XL crude oil pipeline. Montana Attorney General Austin Knudsen in a letter to the president Tuesday urged Biden to reconsider the permit cancellation. Knudsen says the president’s choice deprives states and Montana’s rural eastern counties of future tax revenue. “You’re talking about schools, police, fire departments, and with a stroke of the pen, Pres. Biden says that’s gone. Sorry, thanks for playing," Knudsen says.
