Rep. Rodney Davis, R-Ill., feels lucky to be alive after a gunman opened fire on Republicans practicing for the congressional baseball game on Wednesday.

"I can tell you this is the best Father's Day I've ever had, to be able to come back home and see the outpouring of care and support from the people that know me best, including my family. It's been a really humbling event and very memorable for me and my family," he told "Fox News Sunday."

Davis said he hasn't moved on emotionally from the attack.

"I still sense normalcy," he said. "There are times when I'm probably a little more agitated. There are things I will do differently in my life and in my workplace to ensure that we probably put security more as a priority than we have in the past."

In an interview shortly after the shooting, Davis said he called his wife and children as soon as he was able to get his hands on a phone.

"I told them, ‘I love you and dad's OK,'" he said, becoming emotional.

Four people were shot Wednesday when a gunman opened fire in Alexandria, Va. House Majority Whip Steve Scalise is still in the hospital recovering from his gunshot wounds.
