Meanwhile, the jurors came and went once again Wednesday, reports CBS News Correspondent Steve Futterman. There were no notes, no requests any re-reading of testimony. So far, in four days of deliberations, the jurors have met for more than 18 hours and have asked only one question, on Monday, and the court still has not released the contents of the question.
Jackson's ill health seems to mirror the sorry state of his once-adept PR machine, reports CBS News Correspondent Vince Gonzales.
A controversy over the gag order in the case arose Wednesday when the singer's attorney issued a statement saying he had not authorized anyone to hold news conferences on the pop star's behalf.
The court-approved statement from attorney Thomas Mesereau Jr. appeared aimed at assuring the court that his defense team had not violated the judge's gag order.
Jackson had gone to the emergency room Sunday because of a back problem exacerbated by stress, spokeswoman Raymone Bain said. Wednesday's visit was a scheduled follow-up to that visit, she said in a statement.
"Mr. Jackson is now at home with his family," she said.
About the same time Bain released the statement late Wednesday, one of Jackson's black sport utility vehicles and one of his bodyguards pulled up at the Santa Ynez Valley Cottage Hospital. More than an hour later, the car pulled around the back of the hospital and sped off a few minutes later with its headlights off and curtains drawn.
The departure was similar to one after Jackson's visit to the emergency room Sunday, when his bodyguards erected scaffolding around his car to block reporters' views before the vehicle sped off.
Jackson has complained of a back problem since early March, when he made a morning emergency room visit and raced back to court in his pajama bottoms when the judge threatened to have him arrested.
Jurors were scheduled to resume their deliberation Thursday, which was expected to be a half-day. No reason was given, but the judge noted before the start of deliberations that he understood some jurors had obligations to attend graduation ceremonies for family members.
Jackson, 46, is accused of molesting a 13-year-old cancer survivor in 2003, plying him with wine and conspiring to hold his family captive to get them to rebut a damaging TV documentary about the entertainer.
The confusion inside the Jackson camp was apparent Wednesday as reporters waiting outside the courthouse for a verdict found themselves asking "Who speaks for Michael Jackson?" reports Gonzales.
In the morning, it was Rev. Jesse Jackson, who held his third press conference in three days. He said he meets and prays with the singer.
In the afternoon, it was Bain, who said only she had Mesereau's permission to speak for the singer and his family.
But after she spoke, Mesereau got permission from the court to release a statement on Jackson's Web site: "I have not authorized anyone to speak or hold any press conferences on behalf of Michael Jackson or his family. A gag order is in effect which the defense team will continue to honor."
It is possible that the judge or the prosecution may feel these news conferences are violations of the judge's strict gag order, and that Mesereau's statement may be an attempt to placate the court.
"No one wants to upset the apple cart. This is one of the most critical times of the trial. Tom Mesereau wants to tell everyone, just shut up," said CBSNews.com Legal Analyst Andrew Cohen.
Bain insisted in the wake of Mesereau's statement that it had not been directed at her. She said she runs everything she says by Mesereau and does not violate the gag order because she talks about how Jackson is feeling and not about the case.
Later Wednesday, Jesse Jackson said Mesereau's statement didn't stem from his public comments, either, but that Mesereau had also expressed concerns to him.
"He made it very clear that he wanted to make sure the judge did not think he had a surrogate spokesperson," he told The Associated Press, saying he spoke to the media of his own volition.
"I don't think there will be any impact" on the jury, jury consultant Sam Solomon told CBS News Early Show co-anchor Hannah Storm. "These jurors are smart jurors. They're here for a serious reason. And I believe that these jurors will take that job seriously."
Solomon isn't surprised the jury isn't sequestered, to prevent their exposure to media reports.
"This is an situation where having sequestering doesn't make much of a difference," Solomon said. "These jurors will be focused on jury instructions, how to think about the case. We're finding generally that jurors really take this type of job very seriously."
