President Donald Trump has recently made significant legal arguments regarding his authority, leveraging a Supreme Court ruling that granted him immunity from criminal prosecution. This immunity has been used by Trump's legal team and the Justice Department in various filings, such as the TikTok ban and in Supreme Court cases related to the firing of a government official.
One particular case involves the removal of the head of a watchdog agency on February 7, which will serve as a test of Trump's second-term agenda in the Supreme Court. The Justice Department has asserted that neither Congress nor federal judges have the authority to intervene in Trump's decisions to dismiss appointees of a former president.

The Justice Department has argued that the case represents a challenge to the separation of powers, emphasizing the President's constitutional authority over executive officers he has appointed. The Department has appealed a lower court ruling that sought to prevent the removal of the agency head responsible for protecting whistleblowers.
Trump's legal arguments align with his public statements on the extent of his power, as evidenced by his numerous executive actions and his claims of authority to interpret the law.
