In the early 2000s when he said "thank goodness you're stopping Epstein, everyone has known he's been doing this." The cops were investigating him for soliciting prostitution. Epstein tried to solicit an 18 year old employee of Trump for sex, and that's when he kicked him out of Mar A Logo.
In 2019 when the reporter asked him, Epstein had been indicted for trafficking girls and minors sex including his network of recruiters of young girls. Trump had no idea about this trafficking he was charged with as he hadn't had any contact with Epstein for more than a decade.
So both statements are true and consistent.
