Authorities are still looking for those responsible for planting pipe bombs outside the Republican and Democratic National Committee headquarters last Wednesday and for fatally wounding Capitol Police officer Brian Sicknick, who was struck in the head by a fire extinguisher.

The U.S. Army is investigating an active-duty PSYOP officer who led a contingent of insurrectionists to Washington, D.C., last week. Captain Emily Rainey of the 4th Psychological Operations Group says she led 100 members of a conservative group to D.C. to “stand against election fraud.”

Meanwhile, the Capitol Police department has suspended several officers for their involvement with — or support for — last week’s insurrection, among them an officer who put on a red MAGA hat and directed rioters around the Capitol, and another who posed for selfies with insurrectionists. More than a dozen officers are under investigation.
