The cause of Donald Trump’s erratic behavior has been the subject of rampant speculation for years.
Some have pointed to the hair-loss drug Trump has admitted to taking, others have pointed to a 1992 article in Spy magazine which alleged that Trump was prescribed amphetamines as diet pills by a notorious Manhattan doctor.
This week, two women have come forward with allegations that Trump had unprotected sex with them while he was married. Ex-Playboy model Karen McDougal and porn star Stormy Daniels have both said Trump had unprotected sex with them during the same weekend in Lake Tahoe.
That has led to chatter about an old theory that Trump’s behavior may be tied to untreated syphilis.
