Amid scrutiny of Melania Trump’s immigration status when she first came to the United States, an anti-Trump political action committee announced Thursday that it was filing a public records request for her immigration records.

The group, Democratic Coalition Against Trump, which is made of Democratic officials as well as activists, said Thursday it planned to request “any document that indicates the type of visa applied for or issued to Melania Trump from January 1, 1995 until she received her green card in 2001.”

“After learning that Mrs. Trump might not have followed the law on her path to U.S. citizenship, the Coalition decided to take action,” Jon Cooper, the chairman of the organization said in a statement. “How ironic would it be if Mr. Trump, who has largely based his presidential run on his ridiculously extreme proposals related to illegal immigration, had actually married an illegal immigrant,” Cooper continued. “That would just go to show that Mr. Trump has been and always will be one thing: a hypocrite.”

Politico published a report Thursday raising questions about how Trump had described the process by which she immigrated to the United States when she was working as a model in the 1990s. Trump has said throughout her husband’s campaign that during that period of her career she traveled back to her home country Slovenia every few months to have her visa re-stamped. The Politico report pointed out that the process she described resembled that used by immigrants with a tourist visa, which prohibits working in the United States. A work visa is valid for three to six years, and wouldn’t have required Trump to return to Slovenia regularly to have it re-stamped.

Trump has denied that she broke any immigration laws, but the campaign has not provided specific details about the circumstances of her immigration.
