"Melania does not like being in the public eye and has made it clear that she isn't interested in doing it again," a political source told PEOPLE. "She likes family and her private life. The media glare is not for her."
According to the political source, the 51-year-old was relieved when her husband's presidential term came to an end.
"Nothing has been decided about whether President Trump will run in the next election," the source explained. "At this point it is all speculation."
"The constant chatter about it gives him the opportunity to raise money, which he is very good at doing," the insider noted.
"She is not one bit interested in another campaign, and certainly not participating in it," a social source told the outlet. Melania is said to enjoy her life as it is at the moment.
"She is totally involved with Barron's education, after-school activity and overall well-being," the social source explained. The couple's 15-year-old son recently started school at Oxbridge Academy in West Palm Beach.
"If he runs, I doubt she will be involved at all," the social source said. "If he should win, that would be the worst-case scenario for her. Things will need to be evaluated at such a time."
Melania's office previously told the outlet that she is "enjoying life at Mar-a-Lago. She is focused on being a mother and putting her family first, while working on various projects that will take time to finalize."
An insider told CNN that Melania's time as First Lady is a "chapter" that is "over, and that's that."
"You're not going to see her at rallies or campaign events, even if he 'officially' says he's running again," another source told CNN. "Instead it's going to be Lara [Trump] or [Kimberly] Guilfoyle. They have that same urge Trump has to (run) again; Melania absolutely does not."
Former Trump adviser Jason Miller told Cheddar News last week that the chance of the former Commander-in-Chief running again is "somewhere between 99, 100%." "I think he’s definitely running in 2024," Miller said. However, another presidential bid is not confirmed.
