Former first lady Melania Trump is scheduled to appear for a speech at the National Archives on Dec. 15, Bill of Rights Day, during a ceremony to swear in new U.S. citizens.

At the ceremony, 25 people from 20 countries will be sworn in as new American citizens.

Trump, who was born in Slovenia and became a citizen in 2006, will speak alongside U.S. Archivist Colleen Shogan, in her latest public appearance amid her husband’s third presidential campaign.

The former first lady’s husband, former President Donald Trump, has a troubled relationship with the National Archives as he is facing criminal charges for mishandling classified documents following his departure from the White House in 2021.
