WASHINGTON — The Department of Homeland Security issued a national terrorism bulletin Wednesday warning of the lingering potential for violence from people motivated by antigovernment sentiment after President Joe Biden’s election, suggesting the Jan. 6 riot at the Capitol may embolden extremists and set the stage for additional attacks.

The department did not cite any specific plots, but pointed to “a heightened threat environment across the United States” that it believes “will persist” for weeks after Biden’s Jan. 20 inauguration.

It is not uncommon for the federal government to warn local law enforcement through bulletins about the prospect for violence tied to a particular event or date, such as July 4.

But this particular bulletin, issued through the department’s National Terrorism Advisory System, is notable because it effectively places the Biden administration into the politically charged debate over how to describe or characterize acts motivated by political ideology, and suggests it regards violence like the kind that overwhelmed the Capitol as akin to terrorism.

The bulletin is an indication that national security officials see a connective thread between different episodes of violence in the last year motivated by anti-government grievances, including over COVID-19 restrictions, the 2020 election results and police use of force.

A DHS statement that accompanied the bulletin noted the potential for violence from “a broad range of ideologically-motivated actors.”

“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,” the bulletin said.

The alert comes at a tense time following the riot at the Capitol by supporters of then-President Donald Trump seeking to overturn the presidential election. DHS also noted violent riots in “recent days,” an apparent reference to events in Portland, Oregon, linked to anarchist groups.

“The domestic terrorism attack on our Capitol earlier this month shined a light on a threat that has been right in front of our faces for years,” said Rep. Bennie Thompson, a Mississippi Democrat.
