In a letter obtained by Fox News, 24 Republicans are demanding answers from Defense Secretary Lloyd Austin and slamming the White House administration’s alleged “attack on Christian faith.”

Last week, Walter Reed terminated a contract for pastoral care for its patients and issued a “cease and desist” order to a community of Catholic priests just days before Holy Week, The Catholic Archdiocese for the Military Services said.

The hospital had ended a contract with Holy Name College Friary — a Franciscan community of priests and brothers that has served at the center for nearly two decades.

“Forcing priests to stop providing care during Holy Week is not only morally wrong, but also a violation of the First Amendment,” Republicans wrote in their letter on Wednesday, according to Fox News.
