Limbaugh, who has a residence in Palm Beach County, was named by sources as a possible buyer. He was not the focus of the investigation, according to the sources. 
 
 The radio talk show host said he first became addicted to painkillers "some years ago," following spinal surgery. However, he added, "the surgery was unsuccessful and I continued to have severe pain in my lower back and also in my neck due to herniated discs. I am still experiencing that pain." 
 
 He had tried to break his dependence in the past and has checked himself into medical facilities twice before, he said. 
 
 Limbaugh said that he is "not making any excuses" and that he is "no role model." 
 
 "I refuse to let anyone think I am doing something great here, when there are people you never hear about, who face long odds and never resort to such escapes. They are the role models," he said. 
 
 He would not provide details of his current problem, citing the ongoing investigation. 
 
 "At the present time, the authorities are conducting an investigation, and I have been asked to limit my public comments until this investigation is complete." 
 
 Sources said the investigation began nine months ago when Wilma Cline, a former housekeeper at Limbaugh's oceanfront Palm Beach mansion, approached authorities. 
 
 "I will only say that the stories you have read and heard contain inaccuracies and distortions, which I will clear up when I am free to speak about them," he said. 
 
 Limbaugh has not been charged with any crime. 
 
 Earlier this month, Limbaugh resigned from his position as football commentator on ESPN after making remarks that critics considered racist.
– If Rush Limbaugh doesn't want to absorb some of the cost of female contraception as a health insurance consumer, others are wondering: Why should we pay for Limbaugh's Viagra? "We know" Limbaugh "has used Viagra, which is covered by medical insurance plans," Dr. Nancy Snyderman points out on MSNBC. Limbaugh was detained in 2006 by Customs agents for a mislabeled bottle of the little blue pills crossing the border from the Dominican Republic. Limbaugh said at the time that they were for his personal use, even though a prescription for them was made out to his physician to "protect" his privacy, “given the potential embarrassing nature of Viagra," according to a note from Limbaugh obtained by the Smoking Gun. Snyderman also notes that Limbaugh has been married four times, and has no children, so "I assume he has used some form of contraception." (Limbaugh also entered rehab for an addiction to pain pills, which may or may not have been paid for by health insurance). Limbaugh said last week that Georgetown law student Sandra Fluke's support for insurance coverage for contraception amounted to a demand for payment for sex, calling her a slut and prostitute.
