In a rare public appearance, former first lady Melania Trump stressed the importance of “guarding our freedom” and the responsibilities that accompany American citizenship as she spoke Friday at a naturalization ceremony at the National Archives. Born in Slovenia, Melania Trump is the only first lady who is also a naturalized U.S. citizen. She recounted her path to that citizenship, beginning with a worker visa upon arriving in New York City during her career as a model. "Becoming an American citizen comes with responsibility. It means actively participating in the democratic process and guarding our freedom," Mrs. Trump said. The location of the ceremony was notable. The national repository for presidential documents has featured as part of one of the criminal cases pending against her husband, former President Donald Trump, as he seeks a second term in the White House. The National Archives sent a referral to the FBI stating that 15 boxes recovered from Trump’s Florida home in January 2022 contained dozens of documents with classified markings, part of an investigation that has resulted in 37 counts of mishandling classified documents, including retaining classified information and obstructing justice. Trump's trial is scheduled to begin on May 20, 2024, despite efforts by his team to postpone it until after next November’s presidential election. Friday's ceremony marked a rare appearance for the former first lady, who has said she supports her husband's campaign but has not yet been on the campaign trail as he seeks the 2024 GOP nomination. She said Friday that becoming a U.S. citizen comes with a great deal of responsibility. “It is a life-altering experience that takes time, determination and sometimes even tremendous strength," Mrs. Trump said. In his latest campaign for the White House, Trump has promised a return to hard-line immigration policies if he wins the 2024 election. Among his proposals, Trump wants to revive and expand his controversial travel ban, which initially targeted seven Muslim-majority countries, begin new “ideological screening” for all immigrants and end the constitutional right to birthright citizenship by signing an executive order his first day in office. Friday's ceremony featured 25 people from 25 nations being sworn in as new U.S. citizens, surrounded by founding documents including the Constitution.
