President Donald Trump's New Jersey golf club may have committed federal immigration crimes by handing out fake green cards and social security numbers to workers, according to new evidence collected by prosecutors.

The New Jersey Attorney General's office is investigating the allegations and special counsel Robert Mueller and the FBI are a part of the probe as well.

Attorney Anibal Romero, who represents several undocumented immigrants who used to work at the Trump National Golf Club in Bedminster, says he handed over the fraudulent green cards and social security numbers that the club gave to two of his clients, 45-year-old Victorina Morales and 46-year-old Sandra Diaz, according to the New York Daily News.

Morales and Diaz first came forward in an interview with the New York Times earlier this month saying that Trump's golf club knew they were undocumented and gave them fake work documents.

They are a part of at least five undocumented housekeepers at the golf club who say they were given fraudulent documents as a part of their employment. They also claim they were subjected to racial harassment and abuse at the club.

Romero, a Newark attorney, reached out to Mueller's office to contact federal authorities, before meeting with state prosecutors about the golf club's fake documents.

'I wasn't sure, one, if they'd take me seriously and two, if this could backfire on my clients,' he said to The News.

He added he was hesitant to involve the Justice Department which was led by Jeff Sessions at the time.

He reached out to Mueller's office, which is investigating Trump's presidential campaign for collusion with Russia, and they responded saying the case wasn't within their jurisdiction.

Weeks later an FBI agent in New Jersey called Romero.

'He said to me that he had received a referral from Robert Mueller’s office and that he already knew the specifics and that he wanted to meet with me in person,' he said.

He later met with two agents in New Jersey and shared the evidence he gave to attorney general prosecutors. They then said that they would 'coordinate' with the attorney general's office, the lawyer said.

Romero did not explicitly confirm whether the FBI or the attorney general's office have opened formal investigations.

'I’m confident that federal and state authorities will conduct a complete and thorough investigation,' he said.

Both an FBI spokesman and Mueller's office declined to comment on any investigation.

Diaz is from Costa Rica and used to work at Trump's New Jersey golf club and has since obtained legal status in the U.S.

Morales is a Guatemalan national. She is still employed at the club but has stopped going to work in light of the allegations.

She claims that a supervisor gathered her information and took her picture in the laundry room of the club.

Then a few days later the boss of the golf club told Morales he received her fake documents and he'd keep them.

Victorina Morales says she's coming forward with the fake green card because she's frustrated with President Donald Trump's hypocrisy where he bashes undocumented immigrants yet employs them at the same time. Trump pictured above at the golf club in 2014

The New York Times ran Morales' fake Social Security number through public records and found no match, which they described is 'often an indication that the number is not valid'.

Romero says that the manager's tactic of giving out fake documents and holding onto them deliberately entrapped the workers.

'This was a practice and pattern. My clients felt like they were trapped and they felt like the fake documents could be used against them,' he said.

He added Morales is speaking out, despite the legal troubles it could bring her, because she's frustrated with Trump's anti-undocumented immigrant rhetoric, while he simultaneously employs them at his golf club.

Coming forward is a dangerous move as undocumented workers may have committed immigration fraud by knowingly using fake documents. The offense could land them in jail, or with large fines, or could result in deportation.

The supervisor that procured the documents could also face the same punishment.

'Immigration crimes are hard to prosecute so the government may see something like this as a possible deterrent case. To show that even someone who works at the President’s golf club is under the microscope is very impressive and tells you that anyone can be charged,' Harry Sandick, a former assistant U.S. attorney for the Southern District of New York, said to the News.

But still, Romero hopes that the investigation can unearth a greater problem going on behind Trump's lavish golf club doors.

'They are the victims here. Any attempt at charging them would ignore the real problem,' he said.
