“So help me God” is not part of the oath. But a Muslim cannot take the oath because the only law is Sharia. A muslim cannot swear to preserve, protect, and defend the Constitution.
Doesn’t congress take that oath also? There are Muslim congress critters. It’s ok for them to lie to further Islam.
“So help me God” is optional. Some do, some don’t. 0bama used it on all three occasions. With his hand on Lincoln’s Bible for the first swearing in and then on two Bibles for the second swearing in (Lincoln’s and Rev. M.L. King).
I learned something. Thanks.
