On 27 January 2021, the U.S. Department of Homeland Security issued a National Terrorism Advisory System (NTAS) Bulletin, warning of a heightened threat from domestic extremists, including those who resent the outcome of the 2020 presidential election. The bulletin — the lowest-level of advisory on a three-tier system — is currently set to expire on 30 April and reads in part as follows: “Information suggests that some ideologically-motivated violent extremists with objections to the exercise of governmental authority and the presidential transition, as well as other perceived grievances fueled by false narratives, could continue to mobilize to incite or commit violence.”
