On February 15, 2019, President Trump declared a national emergency concerning the southern border and invoked statutory authority under 10 U.S.C. §§ 2808 and 284 to reallocate Department of Defense funds for border wall construction after Congress refused to appropriate the $5.7 billion he requested. Congress had only appropriated $1.375 billion for 55 miles of fencing in Texas in the February 2019 appropriations bill. The President himself stated: "I didn't need to do this, but I'd rather do it much faster." Three individual plaintiffs (Nayda Alvarez, Leonel Romeo Alvarez, and Yvette Gaytan) are landowners in Starr County, Texas, who received letters from U.S. Customs and Border Protection indicating the government would seek to build a wall on their properties. Frontera Audubon Society is an environmental organization whose members regularly visit areas along the Rio Grande River to observe wildlife that would be impacted by wall construction. Evidence showed that illegal border crossings had declined 76-91% since 2000, with 2017 seeing the lowest number since 1971. The undocumented immigrant population growth had slowed significantly, and undocumented immigrants were arrested and convicted of crimes at lower rates than native-born Americans.
