Fumo was hospitalized on March 2, 2008, after suffering a heart attack at his home. He underwent a successful emergency angioplasty at Hahnemann University Hospital and was released on March 9, 2008. On March 12, 2008, Fumo announced he was dropping his bid for reelection and retiring from public service, citing his federal indictment. On March 16, 2009, a Philadelphia Federal jury convicted Fumo on 137 counts of corruption, conspiracy, fraud and more. Fumo has been the subject of a federal investigation which resulted in his indictment in 2007. The investigation related to a charity run by the Senator called the Citizens Alliance for Better Neighborhoods which was run by a former member of the Senator's staff. In 2004, PECO, a subsidiary of Exelon, donated $17 million to the organization. Federal prosecutors began an investigation as to whether Fumo had forced the utility to make the donation by initially opposing, then supporting, utility deregulation in the state. There were also allegations that Fumo had used the charity's funds for personal benefit. Fumo also suggested that Verizon hire a law firm called Obermayer Rebmann Maxwell & Hippel for a 3-year, $3 million retainer to handle legal work. The chair of Obermayer's litigation committee Thomas Leonard (and a prominent Democrat who served as the city's controller in the 1990s) attended law school with Fumo at Temple University in the 1970s and both have remained friends since then including working on fundraising for Democratic candidates. In late May 2006, two of Senator Fumo’s staffers were arrested and indicted on charges of destroying electronic evidence, including e-mail related to the investigation. The charges were based on e-mails sent by the aides, in which they suggested that Fumo ordered destruction of the documentation. On February 6, 2007, a Federal grand jury named Fumo in a 137 count indictment, alleging mail fraud, wire fraud, conspiracy, obstruction of justice and filing a false tax return. Charges include using state workers to oversee construction of his mansion, spying on his ex-wife, and work on his farm. Additionally, the indictment accused him of misusing $1 million of state funds and $1 million from his charity for personal and campaign use and commandeering yachts from the Philadelphia Seaport Museum for personal travel. Immediately before the indictment was handed down, Fumo resigned his position as the ranking Democrat on the Appropriations Committee and vowed to fight the charges. On March 12, 2008, at a press conference at the Pennsylvania Convention Center in Philadelphia, Fumo announced he was dropping his bid for reelection under stress, saying that the charges against him left "a cloud hanging over [his] head."
