Updated 2:56 pm, Tuesday, January 15, 2013 WASHINGTON (AP) — President Barack Obama is launching the nation's most sweeping effort to curb gun violence in two decades, setting up a legislative fight with a deeply divided Congress that even some of his staunchest allies expect to fall short of its goals. The proposals that require congressional approval will include a ban on military-style assault weapons and high-capacity ammunition magazines along with a requirement for universal background checks on gun buyers. The statewide measure includes a tougher assault weapons ban and provisions to try to keep guns out of the hands of mentally ill people who make threats. Beyond the gun control measures, Biden also gave Obama suggestions for improving mental health care and addressing violent images in video games, movies and television. He also could take steps ordering federal agencies to make more data on gun crimes available and conduct more research on the issue, something Republican congressional majorities have limited through language in budget bills.
