But it's looking like US Attorney General Jeff Sessions does not agree.
When Jeff Sessions announced his intention to rescind the Cole Memo, a Department of Justice policy telling prosecutors to leave legal marijuana states alone, many wondered what President Trump's response would be. And it said it won't speculate about federal decisions.
"What I think may happen is people who otherwise kept their heads down are going to have to stand up and speak out", charged Murphy.
While many states have decriminalized or legalized marijuana use, the drug is still illegal under federal law, creating a conflict between federal and state law.
Seattle Mayor Jenny Durkan has strong words for the Trump administration: "We will not be bullied by an administration that seems obsessed with dismantling things that are actually working", reports CBS.
"Trump promised to let states set their own marijuana policies".
"The cultivation, distribution and possession of marijuana has always been and remains a violation of federal law for all purposes", she later said in a statement.
One issue that may be potentially litigated is how the new memo affects medical versus recreational marijuana use.
The decision, which rescinds previous marijuana prosecution policies, comes just days after the State of California began legal recreation sales of marijuana on January 1.

According to Brown Oregon's marijuana industry has created over 19,000 jobs since it was legalized in 2015.
"Jeff Sessions' obsession with marijuana prohibition defies logic, threatens successful state-level reforms, and flies in the face of widespread public support for legalization", said Maria McFarland Sánchez-Moreno, executive director of the Drug Policy Alliance, a drug reform advocacy group.
But at Green Dragon, Levine said the move won't cause any changes and they won't slow growth plans or scale back any operations.
"It is the mission of the Department of Justice to enforce the laws of the United States, and the previous issuance of guidance undermines the rule of law", Sessions said in a statement. "This is an industry that Oregonians have chosen - and one I will do everything within my legal authority to protect", Rosenblum said.
Marijuana revenue has been used in many ways throughout the state. Just Sessions' announcement has already sparked backlash from politicians on both sides of the aisle, he noted.
The industry's economic contributions means it would be hard to do away with, he said.
The new USA attorney in Massachusetts, Andrew Lelling, a Trump appointee who was confirmed by the Senate in mid-December, called marijuana "a risky drug" in his statement on Sessions' action.
Former Republican Maryland state delegate Don Murphy, who now works in conservative outreach for the Marijuana Policy Project, said the AG's move, presumably sanctioned by Trump, is odd considering the populist wave in favor of decriminalizing marijuana across the country-not only in blue states, but places like Arkansas, the first Bible Belt state to legalize medical marijuana, and with 53 percent of the vote. Effectively, Sessions has rescinded a 2013 guidance issued by then-Deputy Attorney General Jim Cole that limited prosecutions as along as individuals and businesses were operating under their state's laws.
