Fact check: What president has told the most lies?

Checked on June 12, 2025

1. Summary of the results

Based on multiple fact-checking organizations' data, Donald Trump appears to have made significantly more false statements than other presidents. The Washington Post documented over 20,000 false or misleading claims during his presidency, averaging 12 per day [1]. PolitiFact's analysis of his first 100 days showed 17 false statements out of 29 assessed, compared to just 1 from Obama and 2 from Biden [2]. In a broader analysis of 1,000 fact checks, Trump received the highest percentage (18.4%) of "Pants on Fire" ratings among all politicians tracked [3].

2. Missing context/alternative viewpoints

It's crucial to note that presidential dishonesty isn't unique to Trump. Other presidents have made significant false statements that had major political consequences, including George H.W. Bush, Lyndon B. Johnson, and Richard Nixon [4]. Trump's lies are considered unusual because they often lack clear public purpose and appear primarily self-serving, unlike some historical presidential deceptions that may have been motivated by perceived national interests [1].

3. Potential misinformation/bias in the original statement

The question itself presents several potential issues:

  • It assumes that lies can be objectively counted and compared across different eras
  • Modern presidents face much more scrutiny and fact-checking than their historical counterparts
  • The term "lies" implies intentional deception, while some false statements might be misunderstandings or mistakes

Beneficiaries of different narratives:

  • Media organizations and fact-checking websites benefit from tracking and reporting on presidential falsehoods
  • Trump's frequent use of the term "fake news" and attacks on media credibility [5] created a narrative that benefited his administration by allowing them to dismiss unfavorable coverage
  • Opposition political parties benefit from highlighting presidential dishonesty
  • Historical comparisons that emphasize other presidents' dishonesty [4] can benefit current political figures by normalizing such behavior
