The Supreme Court on Monday overturned nearly a century of precedent, ruling in Trump v. Slaughter that multimember regulatory agencies no longer have independence. MSNBC host Rachel Maddow warned the decision radically expands presidential power, allowing the president to fire any agency member for any reason and replace them with loyalists.

Maddow highlighted that liberal Justice Sonia Sotomayor, in her dissent, called the majority ruling "profoundly destabilizing" and stated it "gives the president a power unknown even to the English Crown against which the Founders revolted, elevating him above his once co-equal branches."

The ruling impacts agencies established by Congress to serve as repositories of expertise and technical skill, intended to be insulated from political pressure. Maddow suggested this could allow the president to remove officials from agencies such as the Nuclear Regulatory Commission or the Consumer Product Safety Commission at will.

Maddow pointed to previous instances where she argues the president has leveraged power for personal gain. She cited an example where Reynolds American donated $5 million to a Trump-backed super PAC in April, and the Food and Drug Administration authorized the sale of the company's fruit-flavored nicotine vapes one week later. The same president had called for such vapes to be banned in 2019.

Additionally, Maddow noted that Donald Trump Jr. and Eric Trump secured a financial stake in mining company Dominari Securities, which subsequently received up to $1.6 billion from the U.S. Commerce Department for an overseas mining project. She also raised concerns about Jared Kushner's involvement in U.S. foreign policy toward Saudi Arabia while simultaneously seeking financial investments from the country.

Maddow concluded that the Supreme Court's decision, made in the context of the current president's actions, is not an abstract expansion of power but a specific empowerment of the current administration. The court's decision includes six conservative justices, three of whom were appointed by Trump.
