Discussing how the Obama administration apparently is not controlling illegal immigration and is using terrorist attacks to justify calls for more gun control, Rep. Louie Gohmert (R-Texas) said it is lawmakers’ duty to protect Americans “against all enemies foreign and domestic,” and stressed that Muslim immigrants who believe sharia law (Islamic law) must supplant the Constitution cannot be American citizens.

According to the BBC, “all aspects of a Muslim’s life are governed by Sharia. Sharia law comes from a combination of sources including the Quran, the Hadith (sayings and conduct of Muhammed), and fatwas (the rulings of Islamic scholars).”

As the guest host of Washington Watch radio on Dec. 3, Rep. Gohmert criticized the Obama administration’s handling of illegal criminal aliens in the United States.

“The president has an open, porous border, people are pouring across and we know that some violent people have come across our southern border,” said Gohmert. “So the president has presided over hundreds of thousands, millions really, being in the country illegally, at least 179,000 that, as I understand it, they have detained previously but have let loose on the country who have committed crimes, including murder, rape, robbery.”

Some of those immigrants include terrorists, said Gohmert, and although the administration has “removed some” of them, “there’s a massive number they haven’t.”

“As members of Congress, we are supposed to, we take an oath and we are supposed to be defensive against all enemies foreign and domestic -- the president is,” said Gohmert. “We owe an oath to the Constitution.”

“Then we see reports that some folks, maybe two-thirds of people who believe in Allah, actually would like to see Sharia law take over the place of our Constitution,” he said.

“You cannot be an American citizen and believe Sharia law should supplant our Constitution,” said Gohmert.

Louie Gohmert, 62, is in his sixth term as a member of Congress. Prior to Congress, Gohmert was a lawyer in the U.S. Army, served as a state district judge in Tyler, Texas, and was a chief justice on Texas’s 12th Court of Appeals. A Southern Baptist, Gohmert is married and has three children.
