US lawmakers push for strict checks of gun buyers

Grappling with the deadliest shooting spree in US history, lawmakers said Sunday they want to eliminate a gap between state and federal laws that can allow someone with a history of mental illness to buy guns. Members of Congress have shown little political appetite, however, for attempting to expand federal gun control in response to the massacre at Virginia Tech. Seung-Hui Cho, who gunned down 32 people on campus and killed himself Monday, was evaluated at a psychiatric hospital in late 2005 and deemed by a judge to present "an imminent danger to himself as a result of mental illness." That should have disqualified him from purchasing a gun under federal law, experts say.
