All but 5 Republican members of the Texas House have pledged to defend the state's ban on gay marriage.

On Thursday, a controversial bill which sought to prohibit state or local governments from using public funds to issue marriage licenses to gay and lesbian couples died in the Texas House as a midnight deadline arrived. The following day, House Republicans released a letter signed by 93 out of 98 of its members pledging to continue the fight.

“Traditional marriage is the bedrock institution of both our society and the success Texas has been blessed to experience since our admission as the 28th state within these United States of America,” the letter states.

“We, therefore, affirm the preservation of the present definition of marriage as being the legal union of one man and one woman as husband and wife, and pledge to uphold and defend this principle that is so dearly held by Texans far and wide,” the letter concludes.
