US gun debate: Michelle Obama in emotional gun control plea

US First Lady Michelle Obama has made an emotional appeal for action on gun control, in a speech to community leaders in Chicago.

Mrs Obama cited the case of 15-year-old Hadiya Pendleton, who was mistaken for a gang member and shot and killed in a local park, days after performing at President Obama's second inauguration.

On Wednesday, two US senators brokered a bipartisan deal to expand background checks on gun buyers, boosting the White House's hopes for a firearms control law.
