President Donald Trump has agreed to support efforts protecting state-level laws that legalize the possession, cultivation and distribution of marijuana for recreational use.

According to a report by the Washington Post, President Trump has promised Senator Cory Gardner that he’ll support congressional efforts to protect state marijuana laws that make the plant legal. This ends a months-long standoff between the president and senator which found Senator Gardner blocking all Department of Justice nominations.

Gardner was blocking the nominations based on Attorney General Jeff Sessions’ decision to repeal the Obama-era Cole Memo which gave some protections to state-legal marijuana businesses.

It’s unclear exactly what will come of this, but there’s no denying that it’s a huge step forward for the marijuana reform movement.
