Since she became a Member of the U.S. Senate, Gillibrand's political positions have moved in a liberal direction. In July 2018, "Newsday" stated that Gillibrand "formerly held more conservative views on guns and immigration, but, in her nine years as New York's junior senator, swung steadily to the left on those and other issues". After being appointed to the U.S. Senate, she expressed support for same-sex marriage. Although a supporter of gun rights while in the House, Gillibrand has since moved in the direction of gun control. Gillibrand has said that a conversation with a family who had lost a daughter to gun violence made her realize that she was "wrong" to oppose gun control measures; having once received an "A" rating from the NRA, she received an "F" rating as of 2018. In June 2018, Gillibrand called U.S. Immigration and Customs Enforcement, or ICE, a "deportation force" and became the first sitting senator to support the call to abolish ICE. She said, "I believe you should get rid of it, start over, reimagine it and build something that actually works" and, "I think you should reimagine ICE under a new agency with a very different mission". In May 2018, City & State reported that she had "moved sharply leftward on economic issues, embracing a number of proposals to expand the social safety net and bolster lower-income families". In July 2018, "The New York Times" stated that Gillibrand had "spent recent months injecting her portfolio with a dose of the kind of economic populism that infused Senator Bernie Sanders's campaign in the 2016 presidential primary". In a 2019 reversal of a past position, Gillibrand stated her support for driver's licenses for undocumented immigrants.
