Donald Trump’s mother-in-law immigrated to the U.S. using a process that the former president denounced and sought to scrap, according to a report. His wife, Melania, sponsored her mom, Amalija Knavs, to come to the U.S. using a legal avenue that Trump denigrated as “chain migration,” in which U.S. citizens have the right to sponsor their parents for a green card, according to The Washington Post. Trump said during his presidency that the U.S. needed an “END to the horrible Chain Migration.” Slovenia-born Knavs—who died at the age of 78 in January—became a legal permanent resident in March 2010, the Post reported based on Knavs’ immigration records. She then applied for full U.S. citizenship in August 2017 shortly after Trump took office. In a citizenship test the following year, she reportedly answered enough questions correctly to pass but gave no response to the question: “What is the ‘rule of law?’” She also said she was living in Trump Tower in New York City on her application, according to the Post.
