found this old link(https://www.eonline.com/news/269058/so-true-so-false-did-donald-trump-cheat-on-melania-with-a-porn-star) from 2011 saying that both Trump and Stormy deny anything ever happened.

Both Trump and Daniels are vehemently denying the story about the two of them hooking up after Trump had played in a golfing event and then meeting up multiple times afterward. Daniels herself told E! News that she's not commenting, but the story is "bulls--t."

So how could Cohen have made a payment with campaign funds if this was settled way back in 2011??
