Representative Tim Huelskamp (R-KS) and 28 other House Republicans have introduced a constitutional amendment to prohibit same-sex marriage nationwide.

The proposed "Marriage Protection Amendment" to the U.S. Constitution would read, "Marriage in the United States shall consist only of the union of a man and a woman. Neither this Constitution, nor the constitution of any State, shall be construed to require that marriage or the legal incidents thereof be conferred upon any union other than the union of a man and a woman."

Huelskamp announced he planned to introduce the amendment last week, after the U.S. Supreme Court struck down the federal Defense of Marriage Act and California's Proposition 8.

The amendment needs to be approved by a two-thirds majority vote in both the House and Senate before being ratified by three-fourths of states.

Though a similar constitutional amendment was defeated in 2006, Huelskamp has said he believes there is now more support for banning same-sex marriage nationwide because of the Supreme Court rulings.
