Ohio Governor John Kasich on Tuesday became the 16th candidate to enter the Republican presidential primary.

Kasich announced his bid during a nearly hour-long speech inside the student union building at the Ohio State University, his wife and 15-year-old twin daughters by his side.

“I am here to ask you for your prayers, for your support, for your efforts, because I have decided to run for president of the United States,” he told a cheering crowd.

In an interview with Fox News held immediately after his announcement, Kasich said that the key to his success was his “inclusive” policies.

“Once you have [economic growth] it's a means to an end. So, I think in Ohio, there's been two things that allowed me to be successful. A great team, that goes without saying. But economic growth and a sense that everyone's included. It doesn't matter who you are,” he told Sean Hannity.

Within hours after his announcement, the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, released a video highlighting Kasich's record on LGBT issues.

According to the video, Kasich is opposed to marriage equality, protecting LGBT Americans from discrimination, and gay couples adopting children. Where Kasich stands on bullying and therapies that attempt to alter the sexuality of a gay person or the identity of a transgender person is not clear.

The AP points out that while Kasich backed Ohio's ban on gay marriage, he's also urged public respect for the Supreme Court ruling that struck down bans in all 50 states. Ohio was directly involved in the case.

“I'm very disappointed,” he said last month of the high court's marriage ruling. “I do believe in the traditional sense of marriage.”
