LOUISVILLE, Ky. (WDRB) -- Three-and-a-half weeks after he was attacked outside his home, Kentucky U.S. Senator Rand Paul said on Fox News on Tuesday he was "blindsided" while cutting his grass.

"I was working in my yard with my earmuffs on ... to protect my hearing from the mower," Paul said in his first interview since the attack on Nov. 3. "I'd gotten off the mower facing downhill, and the attacker came running. I never saw him. In fact, the weird thing is I haven't talked to him in 10 years."

Though he didn't name him, police said the attacker is Paul's next door neighbor, Rene Boucher, who is charged with assault.

Paul was left with six broken ribs and fluid in his lungs. He added Tuesday that that fluid was caused by the fact that three of his ribs were displaced, an injury said to be incredibly painful that requires someone to use a breathing machine and do breathing exercises each day.

Since the attack, there's been speculation over what led up to it, with rumors alleging it was either political or a dispute over yard waste. Paul said Boucher indicated why he was upset after he attacked him, Paul isn't revealing just what he said.

"If someone mugs you, is it really justified for any reason?" Paul asked. "And so I think the more people belabored, 'Oh well, is it about yard clipping? Is it because he hates Donald Trump? Is it because you because you oppose Obamacare?'

"You don't really know what's in someone's mind."

It's expected to take several weeks for Paul to fully recover.
