Mia Love Blasts Michelle Obama's 'Hypocritical' Identity Politics: Democrats Recruited a White Male to Take My Seat

Kelly Culbertson saved his girlfriend's life after she was shot in the heart during the Las Vegas massacre last Sunday.

"She told me she was no longer able to breathe," he remembered. "Instinct came in from there."

"I needed to protect her versus other things."

The professional firefighter and EMT went through active shooter training, he told "Fox & Friends."

Culbertson said he disagreed with the push for gun control in the wake of the tragedy.

The focus should "definitely not" be on gun control but on "how selfless everyone has been here," he commented.

"I'm a firm believer in being able to keep those guns," the firefighter said, adding that it might be "helpful" to have more people able to defend themselves.

Culbertson reported his girlfriend has had open heart surgery and is doing well.
