"They're sitting there, and they're looking at Mayor Pete - a 37-year-old gay guy, mayor of South Bend, loves to kiss his husband on the debate stage. And they're saying, okay, how's this going to look, a 37-year-old gay guy kissing his husband onstage next to Mr Man Donald Trump? What's going to happen there?" Limbaugh said. Buttigieg is actually 38.
Separately, Sebastian Gorka, a former deputy assistant to the president and a Trump campaign surrogate, last week questioned on his own radio programme why Buttigieg, "a homosexual man," was "lecturing us about the sanctity of life in the womb."
Buttigieg dismissed the notion that his sexuality could be used against him by Trump in a general-election matchup, noting that he was overwhelmingly re-elected as South Bend mayor after coming out as gay. He added that he believes Americans are in favour of a politics of inclusivity rather than division.
"That's what the American people are for, and I am saddened for what the Republican Party has become if they embrace that kind of homophobic rhetoric," he said on Fox News.
