Some county clerks in New York say they are faced with challenges and concerns now that the Green Light bill passed in Albany, allowing undocumented immigrants to obtain driver's licenses.

"We certainly had a voice in the room,” said Michael Backus, the Oswego County clerk. “I just don't think we were listened to as much as I think we would have liked."

Backus is looking for some direction on how to proceed. So, he wrote a letter to President Donald Trump.

"I think maybe the Justice Department can maybe review it, give an opinion on it and then if it needs to go federal court, maybe they can help us with that,” Backus.

Backus believes the Green Light legislation may violate federal laws.

"The law talks about restricting information being able to be shared from the DMV to immigration agencies and other agencies that may enforce immigration law,” said Backus. “And that's really where the constitutional issue from the U.S. issue comes to play."

Backus says it presents other problems as well.

"My concern is really my staff,” said Backus. “We're not immigration agents. “We don't have the training to go through and look at all of these licenses."

And Backus worries undocumented immigrants may register to vote when they apply for driver's licenses at the DMV.

"At the end of the day, I'm not a judge,” said Backus. “It's not up to me to decide whether this is or isn't constitutional. But I have to uphold both of my oaths. I take an oath to the New York State constitution and the U.S. constitution."

Backus is working with other county clerks and DMV offices as he waits for a response from President Trump. He hopes changes will be made before the law takes effect December 14th.
