Zoltan Tamas, a Romanian father who has worked as a driver for Donald Trump’s family and staff, has been held by Immigration and Customs Enforcement for the past eight months, The New York Times reported on Friday.

The 38-year-old served as a driver for Trump’s children and campaign staff in South Florida during the 2016 presidential campaign, the Times reported. He was a senior security guard at Trump National Golf Club in Jupiter, Florida, and also worked in transportation there.

Tamas, who has a green card, was arrested by immigration agents after applying to be a U.S. citizen in 2016, and a background check found he’d been convicted “in absentia” in Romania for insurance fraud. He has no criminal record in the U.S. since he immigrated here legally in 2011, per the Times.

Now he’s in a legal fight to stay in the country with his wife and two kids, who are American citizens. He hasn’t seen them ― including his 8-year-old daughter, who has congenital heart disease ― since being taken into custody by ICE last summer.

“He was in the country legally, paying taxes and has no criminal record in the United States,” Tamas’ attorney Mario Urizar told the Times. “Why would you keep him detained?”

A few months ago, a judge ordered that Tamas be deported. As his lawyer appeals the decision, he has asked that ICE release Tamas while his case moves through the courts.
