Biden to host unity summit against hate-fueled violence.

Biden will deliver a keynote speech at the gathering, which the White House says will include civil rights groups, faith leaders, business executives, law enforcement, gun violence prevention advocates, former members of violent hate groups, the victims of extremist violence and cultural figures. The White House emphasized that it also intends to bring together Democrats and Republicans, as well as political leaders on the federal, state and local levels to unite against hate-motivated violence.
