TAPPER: In our "NATIONAL LEAD" today, hundreds of activists and DREAMers chanted "home is here" as the Supreme Court heard arguments today that will ultimately determine if nearly 700,000 undocumented immigrants could be deported. The so-called DREAMers were brought to the U.S. as children by their parents and given protections to remain in the U.S. under an Obama era program called DACA. Eliana Fernandez walked 230 miles for nearly two weeks from New York to Washington to make her ploy.</s>ELIANA FERNANDEZ, PLAINTIFF IN DACA CASE: I hope that the justice is going to see our humanity, our worth, and now our contributions that we make to this country as the good Americans we are.</s>TAPPER: The key votes could be Chief Justice John Roberts and the Justice Brett Kavanaugh who today seems sympathetic to some of the Trump administration's arguments today. The case hinges on whether the Trump administration ended the DACA protections for valid reasons. The Supreme Court issuing a major setback today for the gun industry announcing that it will not stop Sandy Hook families from suing Remington, the maker of the Bushmaster AR-15 style firearm used in the 2012 massacre. An attorney for the victim's family says Remington is trying to avoid accountability. 20 children and six adults were gunned down at Sandy Hook Elementary School in Newton, Connecticut in 2012. Because of current laws, many gun manufacturers are protected from wrongful death lawsuits. This case could allow victims' families to sue for damages. A spokesman from Remington could not be reached for comment. You can follow me on Facebook, Instagram, and Twitter @JAKETAPPER or you can tweet the show @THELEADCNN.
