Tuesday was another typical day on the campaign trail for Donald Trump: stoking a new controversy while trying to talk his way around another one, this one involving his wife Melania Trump’s immigration status.

A few hours after the GOP presidential candidate possibly floated assassination imagery regarding Hillary Clinton, he announced that his former wife would hold a news conference “over the next couple weeks” to address reports she violated immigration laws when she first came to the United States, CNN reported.

The Slovenian-born would-be first lady has been dogged by questions about whether she had proper visa authorization to work legally as a model after coming to the United States in the mid-1990s.

She’s also facing scrutiny over how she obtained a green card, considered the “golden ticket” to permanent U.S. residency, four years before she married the real estate mogul/reality star.

“They said my wife, Melania, might have come here illegally. Can you believe that one?” Donald Trump told his supporters Tuesday in North Carolina, hours after suggesting that gun owners could take action to stop Clinton from appointing judges who would infringe on Second Amendment rights, should she be elected president.

“Let me tell you one thing,” Trump said about his wife immigration record. “She has got it so documented, so she’s going to have a little news conference over the next couple of weeks.”

Trump spokeswoman Hope Hicks confirmed to CNN that Melania Trump would hold a news conference, but declined to provide specifics on the timing.

Questions about whether Trump’s immigrant wife worked illegally in the United States emerged after the New York Post published nude photos of the former model. It turns out the photos were taken in New York City in 1995, the year before she has publicly stated that she moved to the United States to work as a model.

Other statements Melania Trump has made, regarding her immigration record in the 1990s, have also raised questions. While telling CNN’s Anderson Cooper that she always obeyed the law, she also said she “flew to Slovenia every few months to stamp” her visa during her early stays in the United States. Immigration experts have told various outlets that these actions are those of someone on a tourist visa — the kind of visa that wouldn’t let her work in the United States.

Additional concerns about Melania Trump’s marriage history and green card emerged after an immigration attorney, working for the Trump organization, told Univision late last week that she obtained a green card in 2001, “based on marriage.” However, Melania and Donald Trump didn’t marry until 2005 in Palm Beach, Florida.

When asked about the discrepancy, the lawyer, Michael Wildes, said he would seek clarification, presumably from the Trump Organization. But he later sent an email to Univision, saying he didn’t “hear back. Sorry.”

The controversy about his wife’s immigration status is a sore point for the GOP presidential nominee, as he has made immigration, especially cracking down on illegal immigrants, a cornerstone of his candidacy.

The gaps and inconsistencies in her story have prompted journalists and Democratic activists to call on Melania Trump to share her immigration documents with the public. In promising a news conference, Donald Trump and his spokeswoman didn’t indicate whether such records would be forthcoming.

Trump, instead, adopted a playful tone about the matter. On the stump, he said he advised his wife to “let it simmer for a little while” before holding a news conference to correct the record.

“Let them go wild. Let it simmer, and then let’s have a little news conference and have some fun,” Trump said.
