US Republican presidential nominee Mitt Romney has named Paul Ryan, who has voted frequently against gay rights, as his running mate.
As Ryan is seen as a social and economic conservative, it is expected he will appeal to staunch Republicans.
Like Romney, Ryan has a long record of voting against gay and human rights.
The Wisconsin politician, like Romney, has voted against marriage equality and adoption by same-sex couples.
In 2004, he voted for amending the US constitution to federally ban same-sex marriage.
