I think youre correct, I found this from memorial day 2019:

Trump, who has been critical of the Ford-class carriers’ new electromagnetic aircraft launch system (EMALS) system, said he prefers the steam-powered catapults found on the older Nimitz-class CVNs. He again called on the Navy to revert back to the old technology while speaking to naval forces in Japan over the Memorial Day weekend.
