Warren was hospitalized Monday after the incident and released Tuesday, said his spokesman, A. Larry Ross. Warren is expected to make a full recovery, Ross said.

"My eyes were severely burned by a toxic poison," Warren wrote in a Twitter message Thursday morning. "Hospitalized Mon. Excruciating pain. Now home. Pray my sight loss is restored."

Though the pain was initially so intense that Warren could not open his eyes on Monday, he was seeing well enough Thursday to send the Tweet himself, Ross said. "The pain was excruciating – 12 on a scale of 1 through 10," Ross said. "It's now down to an 8."

KING: The Obamas are searching, too, for a church, apparently in Washington. They don't have one. Do you think it's important for the public to see their leader go to church?

WARREN: I think it's important for the public to see our leaders having faith. I think it expresses a sense of humility that says, I recognize that I'm not the end all, be all.

WARREN: No. In fact, I told the president that. I'm a friend and I'm a prayer partner, but I'm not a consultant. I'm not a pundit. And it's not my role to do that. My role is to help people in their personal lives. I have helped a lot of leaders, both locally and globally, with issues about family and issues about personal stress. That's a pastoral role. I'm a pastor, as you know, Larry. I'm not a politician and I'm not a pundit.

I care about each person individually, whether I happen to agree with them or not. We all have the same basic needs. We all want to be loved. We all want to have a place of service. We all want our lives to count. We all want to know our purpose in life. These are things that everybody deals with.
