Hours after the U.S. Supreme Court paved the way for same-sex marriage bans to be lifted in five states, U.S. Sen. Ted Cruz called Monday for amending the U.S. Constitution to prevent either the federal government or the U.S. Supreme Court from overturning a state's ban on same-sex marriage.

Cruz announced his plans in a statement Monday in response to the U.S. Supreme Court's decision to let stand appeals court rulings allowing same-sex marriages in Indiana, Oklahoma, Utah, Virginia and Wisconsin. Cruz called the court's decision to let those rulings stand "tragic and indefensible" and expressed concern that it would lead to the overturning of same-sex marriage bans in every state.

Like other statewide Republican officials in Texas, Cruz has been an ardent defender of the state's same-sex marriage ban, which was approved by Texas voters as an amendment to the Texas Constitution in 2005. The Texas ban was ruled unconstitutional by a U.S. District Judge in February. The state immediately appealed that ruling to the 5th Circuit Court of Appeals.

"When Congress returns to session, I will be introducing a constitutional amendment to prevent the federal government or the courts from attacking or striking down state marriage laws," Cruz said. “Traditional marriage is an institution whose integrity and vitality are critical to the health of any society. We should remain faithful to our moral heritage and never hesitate to defend it.”
