AI Overview
Donald Trump disregarded a number of long-standing presidential norms and precedents related to ethics, the separation of powers, and political conduct. While not always legally binding, these traditions have historically been followed to ensure accountability, prevent conflicts of interest, and maintain public confidence in democratic institutions.

Key norms and precedents disregarded by Trump include:

Financial and Ethical Norms<

Refusal to divest business holdings: Unlike his predecessors who placed assets in a blind trust, Trump retained full ownership of his global business organization, transferring only management, not ownership, to his sons. This led to thousands of potential conflicts of interest, as foreign and domestic government entities spent money at his properties.

Failure to release tax returns: Trump was the first major-party presidential nominee in 40 years not to release his tax returns for public inspection, breaking a norm of transparency.

Use of office for personal benefit: He faced criticism for using his official position to promote his private businesses and for receiving payments from the federal government (e.g., the Secret Service) at his properties, which critics argued violated the Constitution's Domestic Emoluments Clause.

Separation of Powers and Rule of Law

Challenging judicial independence: Trump frequently and publicly criticized judges and court rulings that went against his administration, at times calling a judge a "so-called judge".

Impounding Congressionally-approved funds: His administration paused or canceled billions of dollars in foreign and federal funding that had been authorized by Congress, an action a federal judge blocked and which drew comparisons to actions by President Nixon that led to the Impoundment Control Act of 1974.

Pressure on law enforcement and the Justice Department: He repeatedly pressured the Attorney General and the Justice Department to investigate political rivals or to limit the Special Counsel investigation into Russian interference, actions considered a breach of norms protecting the DOJ's independence.

Abuse of pardon power: Trump used his pardon power extensively in his final days in office to grant clemency to political allies and supporters, including some convicted of fraud and January 6th rioters.

Political Conduct and Democratic Institutions

Attacks on election integrity: Following his 2020 loss, Trump engaged in an unprecedented effort to subvert the election results, including spreading false claims of widespread fraud, pressuring state election officials to "find" votes, and attempting to coerce the Vice President to unlawfully override the Electoral College process.

Incivility and personal attacks: He regularly used social media and campaign rallies to personally attack opponents, critics, the press, and even members of his own administration with belittling nicknames and language widely considered "unpresidential".

Undermining the press: Trump frequently labeled mainstream news organizations as the "enemy of the people" and "fake news," limiting press access and challenging the traditional role of a free press in a democracy.

Mass firings of independent officials: He fired a number of inspectors general and members of independent agencies (such as the National Labor Relations Board) without consulting Congress, actions that were challenged in court.
