Investigators have made significant progress in a case that has puzzled authorities for nearly five years. Brian Cole Jr., 30, confessed to placing pipe bombs outside the headquarters of the Republican and Democratic parties just before the January 6 Capitol attack. Cole expressed his belief in the theft of the 2020 presidential election and his support for Trump during his interviews. Federal officials have not yet clarified if there are links between the pipe bomb placement and the Capitol riot. His arrest highlights a turning point in unraveling events surrounding the Capitol attack, as the FBI successfully tracked him through credit card transactions tied to bomb-making materials.
