There is a more interesting reason. WSJ also published a story of Trump lawyer paying $130,000 hush money in October 2016 to a _pornstar for a 2006 Lake Tahoe rendezvous: Trump Lawyer Arranged $130,000 Payment for Adult-Film Star’s Silence Consensual.

I changed BC to BCE; then they were reversed by one fellow who seems to be contributing a lot to the page saying that it is annoying. I pointed out...
