Sen. Rand Paul (R-KY) was present at a congressional baseball practice in Alexandria, Va., when House Majority Whip Steve Scalise and multiple others were shot.
Paul said a massacre could have unfolded if Scalise's security team was not there.
He that he was in the right field batting cage area when the shooting started from near the third base dugout.
He said that he "vaguely" saw the gunman before the shots started.
Paul said just minutes earlier, he was in the area where the shots were coming from but walked to the batting cage area to hit.
He described hearing 50 to 60 shots go off. He said after several minutes, the Capitol Hill police, who were there as part of Scalise's security detail, began returning fire.
"I do believe that without the Capitol Hill police, it would have been a massacre," he said. "We had no defense at all."
