Melania Trump released a letter on Wednesday from an immigration lawyer asserting that there is “100% certainty” that she immigrated to the United States legally.

“I am pleased to enclose a letter from my immigration attorney which states that, with 100% certainty, I correctly went through the legal process when arriving in the USA,” she tweeted.

A Politico report in August questioned Trump’s immigration status, highlighting a period in her career when she appeared to be working in the United States on a tourist visa.

“I can unequivocally state that these allegations are not supported by the record, and are therefore completely without merit,” attorney Michael J. Wildes writes in the letter.

Wildes also disclosed in the letter that he previously represented Trump Model Management, which has faced its own questions about employing models without work visas. Former Trump models told Mother Jones in an August report that the agency knew they were working in the country without the proper documentation.

Trump did not release any other documents regarding her immigration status.
