The suspect arrested Thursday morning in connection with the planting of pipe bombs outside the Democratic and Republican National Committees on the eve of the Jan. 6, 2021, Capitol riot may have had “anarchist leanings,” federal law enforcement sources told The Post. Federal agents swarmed the Woodbridge, Va., home of 30-year-old Brian Cole Jr. following the break in the case that has vexed and embarrassed the FBI for nearly five years. It was not immediately clear what charges Cole would face and investigators have not gone public with any suspected motive.
