The Atlanta Journal-Constitution is reporting that T.I. is expected to file a guilty plea today in response to multiple Federal weapons charges against him, and that he “faces certain prison time” as a result. T.I.–born Clifford Harris–has been under house arrest since October, when he was arrested in a weapons sting. The plea is scheduled for 1:30 p.m. ET, with his sentencing scheduled for a later date; the Associated Press’ sources are claiming that his sentence will involve 1,500 hours of community service–during which he’ll speak to youth groups around the country “about the pitfalls of guns, gangs and drugs”–and 12 months in the federal pokey, which could be shortened if he’s on good behavior.
