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.
