The speech ended with a history making kiss with his husband.
In an emotional speech that ended in a kiss with his husband Chasten Glezman, Mayor Pete Buttigieg from South Bend, Indiana officially threw his hat in the presidential race on Sunday.
If elected, Buttigieg would be the first openly gay president in America.
The 37-year-old was elected as Mayor of South Bend in 2012. He is an Afghanistan war veteran whose education includes Harvard University, Pembroke College, and Oxford on a Rhodes Scholarship.
The candidate is growing in popularity in his party, he placed third among Democratic voters last week in a New Hampshire presidential primary poll, just behind Joe Biden and Bernie Sanders.
The announcement is likely to exacerbate hostility from some religious conservatives who have already denounced Buttigieg because of his sexual orientation.
Andrew Bieszad, a right-wing pundit and journalist for far-right website Shoebat.com called Buttigieg too “effeminate" to run for the presidency and “A sodomite whose name means ‘the king of cocks...’"
But the couple's supporters are perhaps drowning out the homophobia with words of encouragement and support after seeing his speech and kiss on Sunday.
Journalist LZ Granderson tweeted, "Trying to imagine what it would have been like to see this image on the national political stage growing up. Thanks to @PeteButtigieg no generation that follows will have to imagine..."
"I love this photo of Pete Buttigieg and his husband Chasten Glezman," wrote Tom Knight. "It sends a powerful message to every gay kid in the world that they can be anything they want to be, no matter what people tell them."
