'There is no defence for this' UFC's Dana White after hitting his wife

UFC President Dana White took responsibility in a news conference Wednesday for slapping his wife, Anne, on New Year's Eve.

"There are no excuses for it," he said. "It's something I'm going to have to deal with and live with for the rest of my life.

"There's no defense for this, and people should not be defending me over this thing, no matter what. All the criticism I have received this week is 100% warranted and will receive in the future."

White was caught on video made public by TMZ slapping his wife while they vacationed in Cabo San Lucas, Mexico. The video shows his slap came as a retaliation after she slapped him first. Others at the party then intervened.

White said he would not self-impose a punishment.

"What should the repercussions be?" he asked, rhetorically. "I take 30 days off? How does that hurt me? ... Me leaving hurts the company, hurts my employees, hurts the fighters. It doesn't hurt me."
