Pro Publica points out while Trump has Pulte going after people who said a property was their primary residence and wasn't, Trump has done that repeatedly himself.
In fact in 1993 Trump did it twice in 7 weeks. Got a mortgage on a property in Florida saying it was his primary residence, NEVER lived there, and 7 weeks later got another property and claimed it was his primary residence, and has never lived there. Those were the 2 Pro Publica called out but there were MULTIPLE other cases of this by Trump himself.
