Welllllllllll ... if you actually click through to the actual source of this claim - which I doubt (m)any DUpipo did, you find:
Mr Cohen comes to WashingtonThere are rumors, too, of Trump mistresses paid to have abortions and kept quiet with non-disclosure agreements. One source tells Cockburn that there could be as many as eight such women. (Cockburn should point out that Trump has been the subject of rumors about secret abortions for years, and has admitted no such thing.) ...
This is from a series of columns subtitled, "Mischief, mayhem and Washington gossip".
So this claim - published 3 or 4 months ago, BTW - is, in the words of the source, "rumors" from a "gossip" column.
When's
Kitty Litter Kelly's Trump bio going to be published?
