The linked Daily Mail article has nothing about Pelosi. It has pics from Emma Coronel visit to Venice (Pelosi is not in any of them) and lots of whiny @#$% about the prison in which El Chapo is being held.
So the only verifiable facts at present are that Emma Coronel and Nancy Pelosi were in Venice around the same time. Venice is a big city and a popular destination for tourists and business. I'd love for Coronel to be spending a few involuntary years on Alcatraz, and Pelosi a similar time marooned on the Farallon Islands, but realistically, as rumor-grade stuff goes, this is pretty tenuous.
