Jan. 9 (UPI) -- Brian Cole Jr. pleaded not guilty Friday to federal charges accusing him of placing pipe bombs outside political party headquarters ahead of the Jan. 6, 2021, Capitol protest.

Cole entered his plea during an arraignment hearing in the U.S. District Court for the District of Columbia. He faces charges of interstate transportation of explosives, malicious attempt to use explosives and related federal charges.

Cole, 30, allegedly placed a pipe bomb near the entrances of the Republican National Committee and Democratic National Committee headquarters in Washington, D.C., on the night of Jan. 5, 2021, but neither exploded.

Federal prosecutors said he admitted to placing the explosive devices and that he hoped they would explode and generate news coverage.
