President Donald Trump’s administration will work to relax federal marijuana laws and regulations after the midterms, according to one of his staunchest Republican defenders in the House.

Rep. Dana Rohrabacher of California told Fox Business on Thursday he has worked to secure a “solid commitment” from administration officials to legalize medical marijuana across the federal level and leave recreational use of the drug up to the states.

“I have been talking to people inside the White House who know and inside the president’s entourage. … I have talked to them at length. I have been reassured that the president intends on keeping his campaign promise,” Rohrabacher said.

Trump had signaled on at least three separate occasions during the 2016 presidential campaign that he would leave recreational marijuana laws up to the states and that he could favor opening up medical marijuana usage at the federal level.

“I think it certainly has to be a state — I have not smoked it — it’s got to be a state decision,” Trump told WWJ Newsradio 950 in Michigan in March 2016.
