US Security Officials Warn of 'Heightened' Domestic Threat Jeff Seldin U.S. security officials warn ongoing anger over the outcome of the recent presidential election, as well as other grievances, could fuel new violence across the country in the coming weeks and months. The Department of Homeland Security on Wednesday issued a National Terrorism Advisory System (NTAS) Bulletin, cautioning that a "heightened threat environment" was likely to persist through the end of April. "Violent riots have continued in recent days and we remain concerned that individuals frustrated with the exercise of governmental authority and the presidential transition, as well as other perceived grievances and ideological causes '¦ could continue to mobilize," DHS said in a statement, not giving any details. The [1]bulletin further warned that violent domestic extremists "may be emboldened by the Jan. 6, 2021, breach of the U.S. Capitol in Washington, D.C., to target elected officials and government facilities."
