“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 department said.

The National Terrorism Advisory System Bulletin said a heightened threat of attack “will persist in the weeks following the successful presidential inauguration,” which took place on January 20.

“DHS does not have any information to indicate a specific, credible plot,” it said.

“However, violent riots have continued in recent days and we remain concerned that individuals frustrated with the exercise of governmental authority and the presidential transition… could continue to mobilize a broad range of ideologically-motivated actors to incite or commit violence.”
