The U.S. Department of Homeland Security is reviewing "a number" of complaints that its agents used excessive force against anti-racism
protesters in Portland, Oregon, though so far no one has been disciplined, the department's acting head said on Thursday.
Acting Secretary Chad Wolf testified to the U.S.
Senate Committee on Homeland Security and Governmental Affairs about the federal response to long-running
protests in Portland, where state and city officials complained that the presence of federal officers inflamed protests.
