Ellen Segal Huvelle, a federal judge in the U.S. District Court for the D.C. District, ordered Abramoff to serve 48 months in addition to the two years he already served for a separate case, The Hill, a Washington political publication, reported.

Abramoff had pleaded guilty to corruption charges involving lawmakers, including some that involved defrauding Indian tribes of tens of millions of dollars, The Hill said. Federal prosecutors had sought a prison sentence that was less than the potential maximum of 11 years because the one-time Washington power-broker had been cooperating with the U.S. Department of Justice.

"I come before you today as a broken man," Abramoff told the court. "I'm not the same person who happily and arrogantly engaged in a lifestyle of political and business corruption."
