What the Evidence Shows
The claim that Karoline Leavitt married her father is factually incorrect. Multiple reliable sources confirm that Karoline Leavitt married Nicholas Riccio in January 2025. While there is a notable age gap of approximately 32 years between Leavitt and Riccio, this has led to public commentary and media coverage about their 'atypical' marriage, but there is no familial relationship such as father-daughter between them.
Karoline Leavitt's husband, Nicholas Riccio, is significantly older than her, but he is not her father.
Her actual parents, Bob and Erin Leavitt, have been married since 1989 and are close in age to her husband but are distinct individuals from Riccio.
The media coverage focuses on the age gap and the dynamics of their marriage, not any incestuous or familial marriage claims.
Therefore, the statement is a misrepresentation of the facts surrounding Karoline Leavitt's personal life.
