While President Donald Trump was keeping the government shut down for weeks over the need for a border wall to bar potential immigrants, his golf club in Westchester County was quietly firing a dozen undocumented employees, some of whom had been there for years.

According to a Saturday Washington Post report, the firings at the Trump National Golf Club in New York happened one after another starting January 18.

Managers told the employees that the company had audited their papers—some which had been submitted years before—and found them to be fake.

Per the Post, accountants at the golf club had looked the other way for years over the phony papers, one former manager describing the policy as “don’t ask, don’t tell” to keep labor costs cheap.
