Wisconsin Rep. Paul Ryan on Friday reiterated his support for the Employment Non-Discrimination Act (ENDA), which would outlaw workplace discrimination based on sexual orientation and gender identity.

When asked by ThinkProgress.org his position on the measure, Ryan said, “Oh, ENDA. I voted for that before.”

“My position is very clear on ENDA,” he said.

Ryan, a Republican, could not answer why most Republicans don't support the bill: “I think it's just, there are Republicans who support ENDA. I was one of them. I don't know the answer to the question.” (The video is embedded on this page. Visit our video library for more videos.)

ThinkProgress.org disagreed with Ryan, saying his position wasn't all that clear. His 2007 vote for the bill is his lone accomplishment on gay rights. And Ryan personally lobbied the bill's sponsor, former Massachusetts Rep. Barney Frank, to strip transgender protections from the measure. During the 2012 presidential campaign, Ryan, Mitt Romney's running mate, refused to say whether he would vote for a trans-inclusive version of the bill.
