On February 9, 2009, prosecutors filed a motion in federal court to revoke Barry's probation for not filing his 2007 tax return, which violated his probation. According to one prosecutor, Barry has not filed his taxes eight of the last nine years. Barry said the reason he did not file his taxes is because of distractions from his medical problems, although he noted that there is "no excuse" for not filing. In an interview, Barry said he had been undergoing four-hour dialyses three times a week as treatment for a problem with his kidney. At that point, a kidney donor had been identified, but the operation had yet to be scheduled. On February 17, WTOP-FM reported that, according to Barry's attorney, Barry had filed his federal and District tax returns for 2007. The same day, Barry was admitted to Howard University Hospital to prepare for a kidney transplant the next day. Barry was released from the hospital on February 27, but he was readmitted on March 2 due to large amounts of air in his abdominal cavity and also due to Barry's complaints of serious pains, both of which were caused by the combination of medications Barry was taking after the operation. Barry was released from the hospital on March 6. On April 17, 2009, the prosecution withdrew their request to revoke Barry's probation.
