US Republican Ben Carson has come under increasing criticism over his statement that he would not favour electing a Muslim as US president.
According to The Washington Times, Texas Republican Ted Cruz stated that Carson's remark was inconsistent with the U.S. constitution, saying "the Constitution specifies there shall be no religious test for public office".
Cruz's statement came at the taping of an Iowa Public Television program.
Carson did not say a Muslim cannot legally be president or that there should be a religious test for office, but he doubled down later in the evening, telling The Hill that belief in Islamic law is inconsistent with the U.S. Constitution.
