President Joe Biden will announce the creation of the first-ever federal office of gun violence prevention on Friday, fulfilling a key demand of gun safety activists as legislation remains stalled in Congress, according to two people with direct knowledge of the White House’s plans.

Stefanie Feldman, a longtime Biden aide who previously worked on the Domestic Policy Council, will play a leading role, the people said.

Greg Jackson, executive director of the Community Justice Action Fund, and Rob Wilcox, the senior director for federal government affairs at Everytown for Gun Safety, are expected to hold key roles in the office alongside Feldman, who has worked on gun policy for more than a decade and still oversees the policy portfolio at the White House. The creation of the office was first reported by The Washington Post.
