JUNEAU, Alaska — Governors in at least two states that have legalized recreational marijuana are pushing back against the Trump administration and defending their efforts to regulate the industry.Alaska Gov. Bill Walker, a one-time Republican no longer affiliated with a party, sent a letter to U.S. Attorney General Jeff Sessions this week asking the Department of Justice to maintain the Obama administration’s more hands-off enforcement approach to states that have legalized the drug still banned at the federal level.It comes after Sessions sent responses recently to the governors of Alaska, Colorado, Oregon and Washington, who asked him to allow the pot experiments to continue in the first four states to legalize recreational marijuana. Sessions detailed concerns he had with how effective state regulatory efforts have been or will be.Washington state also responded to Sessions this week. Gov. Jay Inslee said the attorney general made claims about the situation in Washington that are “outdated, incorrect, or based on incomplete information.”“If we can engage in a more direct dialogue, we might avoid this sort of miscommunication and make progress on the issues that are important to both of us,” Inslee and that state’s attorney general wrote to Sessions.
