The rate of incarceration in the U.S. is the world's highest, leading to what many lawmakers and policy analysts say is a nationwide imprisonment epidemic. But the beginning of the end of that epidemic started Tuesday, Rep. Hakeem Jeffries, a Democrat from New York, told VOA. A bipartisan prison reform bill that passed the U.S. House of Representatives by a 360-59 vote "strikes an opening blow against the overcriminalization of the nation," Jeffries, one of the bill's co-sponsors, said. U.S. President Donald Trump said "the strong bipartisan vote paces the way for action by the Senate." Last week, Trump endorsed the bill at a White House summit on prison reform, saying, "Our whole nation benefits if former inmates are able to reenter society as productive, law-abiding citizens." If the bill reaches the president's desk for a signature, it would provide $50 million in funding for five years to provide job training, education and substance abuse treatment for prisoners as well as a number of quality-of-life measures aimed at reducing chronically high rates of recidivism among former inmates. But the contentious issue of criminal justice reform has split Democrats and Republicans within their own parties, possibly jeopardizing the bill's chances of passage as it heads to the U.S. Senate. In a letter to colleagues last week, Democratic Senators Kamala Harris, Dick Durbin and Cory Booker joined two House Democratic colleagues, Representatives John Lewis and Sheila Jackson Lee, in saying the bill could not be implemented effectively and could possibly lead to prison privatization. Jeffries told VOA many of the arguments against the First Step Act "were anchored in falsehoods." He added the legislation passed today "is a first step towards eradicating the cancer of mass incarceration" a move also welcomed by many House Republicans. "Rather than allowing the cycle of crime to continue, this legislation takes a practical, intelligent approach to rehabilitation," House Judiciary Chairman Bob Goodlatte, a Republican... Why were some Democratic Senators opposed to passage of the First Step Act? - they did not think it could be successfully implemented and might lead to the prevalence of private prisons - they opposed the bipartisan support that the bill received - not enough information - they disagreed that mass incarceration was an issue
