	In February 2019, Congress amended an existing appropriations bill to protect several sites along the border, including the historic La Lomita Chapel in Mission, Texas. Trump's declaration of a national emergency could remove those protections. The local pastor, Roy Snipes, and his bishop, Daniel E. Flores, oppose the plan to use church property for the wall, and the Brownsville diocese has challenged it in court. The Georgetown University Law Center's Institute for Constitutional Advocacy and Protection (ICAP) filed a brief in support of the diocese. In a show of support for the chapel, over a thousand parishioners held a procession on Palm Sunday, April 14, 2019, from Our Lady of Guadalupe Church to the chapel.
