Once upon a time, Trump was against extreme vetting
From The Art of the Deal:
To buy an apartment in a condominium, all you need is the purchase price. To buy a cooperative—which is what most buildings in New York were at the time—you need approval from its board of directors, who have ridiculous, arbitrary powers, including the right to demand all kinds of financial data, social references, and personal interviews. They can reject you for any reason they choose, without explanation. It’s a license to discriminate. The worst part is that many people on these co-op boards get their kicks from showing off their power. It’s absurd and probably illegal, but it happened to be great for Trump Tower. Many wealthy foreigners didn’t have the proper social references for these cooperatives, or didn’t want to put themselves through the scrutiny of a bunch of prying strangers. Instead, they came to us.
