I haven’t really been keeping up with RFRA, or what it even stands for so I let Google do the walking. I am still now more confused and it is a Saturday, but here is the first passage in the wiki entry:

The Religious Freedom Restoration Act of 1993, Pub. L. No. 103-141, 107 Stat. 1488 (November 16, 1993), codified at 42 U.S.C. 2000bb through 42 U.S.C. 2000bb-4 (also known as RFRA), is a 1993 United States federal law aimed at preventing laws that substantially burden a person’s free exercise of religion. The bill was introduced by Congressman Chuck Schumer (D-NY) on March 11, 1993 and passed by a unanimous U.S. House and a near unanimous U.S. Senate with three dissenting votes[1] and was signed into law by President Bill Clinton.

The RFRA was held unconstitutional as applied to the states in the City of Boerne v. Flores decision in 1997, which ruled that the RFRA is not a proper exercise of Congress’s enforcement power. However, it continues to be applied to the federal government—for instance, in Gonzales v. O Centro Espirita Beneficente Uniao do Vegetal—because Congress has broad authority to carve out exemptions from federal laws and regulations that it itself has authorized. In response to City of Boerne v. Flores, some individual states passed State Religious Freedom Restoration Acts that apply to state governments and local municipalities.
