Louisiana Governor Bobby Jindal on Wednesday officially announced that he is running for president in 2016.

“I'm running for President of the United States of America,” he messaged followers on Twitter ahead of a formal announcement in Kenner, a suburb of New Orleans.

Jindal is the 13th candidate for the Republican presidential nomination, with several more expected to follow.

The Washington Post notes that Jindal's “chances of winning the GOP nomination seem extraordinarily low” and points out that Jindal came behind “None of the Above” in the most recent Fox News poll of candidates.

Like all of his Republican rivals for the GOP nomination, Jindal does not support marriage equality. (Former New York Governor George Pataki has not publicly stated his position on the issue, saying only that the issue of marriage should be left up to the states. As governor, he signed a gay protections bill.)

Jindal also recently made headlines when he issued an executive order mere hours after Louisiana lawmakers shelved a controversial “religious freedom” bill that sought to prohibit the government from taking adverse action against a person for expressing a religious belief or moral conviction about marriage. Jindal's order closely mirrors the proposed bill.
