John Rich, of Big & Rich, performed at the Route 91 Harvest Festival shortly before shots rang out at the show.
The country star was hanging out at the Redneck Riveria bar, which he owns, after his performance when the crowd at the festival was barraged with bullets.
The gun owner gave his weapon to an off-duty cops officer.
Rich told Fox News on Monday,”I had a Minneapolis cops officer off-duty hanging out. He came up to me and he showed me his badge and he says, ‘I’m officer… and I am not armed for the 1st time ever I can’t believe it. Are you armed? I said, ‘Yes sir, I am armed.’ I have my concealed weapons permit and I said, ‘Yes, I am armed.’ He said, ‘Can I have your firearm so I can hold point on this front door?’
Rich desribed the scene at his bar.
“So, I handed over my firearm to him and everybody got behind him for about two hours without flinching this guy kept a point on in that front door just in case somebody came through,” Rich recalled.
The singer asserted Sunday evening’s tragedy was “an attack on America.”
