What are the disqualifications for a US passport?

Answer 1

A passport is a document that certifies a person's citizenship. It is
not a guarantee of character or anything else; it is basically an
identity document. In fact, the passport form doesn't even ask the
applicant about criminal history.

Traditionally, there is just one type of felony that would prevent the
person from getting a passport. A person is ineligible if he or she
has "been convicted by a court or court martial of competent
jurisdiction of committing any act of treason against, or attempting
by force to overthrow, or bearing arms against, the United States, or
conspiring to overthrow, put down, or to destroy by force, the
Government of the United States."
