Sara Groves' family spring-break vacation to Missouri with her husband and three children took a sudden detour when the Christian singer from Burnsville got invited to perform at the White House Easter prayer breakfast on Wednesday. "I found out late in the game so I didn't have time to get nervous," Groves said after her performance. There was a 7 a.m. sound check, a private tour of the Rose Garden and photos with President Obama. She sat at the piano and performed her own "He's Always Been Faithful" and then a verse and chorus of the hymn "Great Is Thy Faithfulness" in front of more than 150 people, including the president and such religious leaders as the Rev. Al Sharpton and Dr. Cynthia Hale. "It was a very enjoyable morning," Groves said. "For not knowing anybody in the room, the feeling of community was strong." Afterward, Groves and her husband/manager Troy Groves met with representatives from the president's Office of Faith Based Initiative. While driving home Wednesday evening, Groves said by telephone that the president complimented her singing, calling it "lovely, beautiful, very moving." They chatted briefly about human trafficking issues, which is one of her campaigns. "To me, it's the gospel," she said. "How do you tell a girl in a brothel that God loves her?"

Final autopsy report released for Houston

Whitney Houston was found face-down in a bathtub with cocaine in her system and drug paraphernalia on the bathroom counter nearby, investigators revealed in the singer's final autopsy report released Wednesday, in a grim accounting of her final hours nearly three months ago. The singer had complained of a sore throat and an assistant suggested she take a bath before the start of a pre-Grammy Awards gala. By the time the assistant returned, Houston had drowned, having been submerged for at least an hour, the report said. Water soaked the floor, seeping into the bedroom. Investigators found in the bathroom a "spoon with a white crystal like substance in it," and a white powdery substance in a drawer and on a mirror, the report said. The report does not identify the substances, although toxicology tests discovered cocaine in Houston's heart and extremities. The report provides a sad footnote to Houston's life, revealing the toll the singer's drug use took on her body, including a hole in her nose. Beverly Hills police Lt. Mark Rosen said the investigation is still open and that he could not comment on the findings. The department has said there did not appear to be signs of foul play. Investigators initially expected drugs or alcohol played a role in Houston's death, but no alcohol was found in her system. They eventually ruled her death an accidental drowning, with heart disease and cocaine use cited as contributing factors.
