Does a person running for President of the USA need to pass any medical examination?
Nowhere in the Constitution does it require the President to undergo any kind of medical examination to qualify for office.
Article II, Sec. 1 states that the qualifications for President are as follows:
- Must be at least 35 years of age.
- Must be a natural-born citizen of the United States.
- Must have been a resident of the United States at least 14 years.
Additionally, the 20th and 25th amendments establish a line of succession upon death or disability of the President while in office, but do not affect the actual qualifications to be elected.
To require any other kind of qualification for the office would require a constitutional amendment. It could not be imposed as a simple matter of law.
In recent years, Presidential candidates have been subjected to increased scrutiny regarding their age and health. Concerns over John McCain's age and an alleged cover-up of Hillary Clinton's deteriorating health have made news cycles. Bernie Sanders' age has also been cited as a concern.
Additionally, a lot of rhetoric has been stirred up regarding candidates' past financial dealings, causing some candidates to disclose their federal tax returns.
All of these issues, however, are a matter of political wrangling, not a matter of law. The Constitution makes no requirement for any qualification beyond what is outlined above.
