WOODBRIDGE, Va — The FBI swooped into this Washington, DC suburb on Thursday and arrested a Virginia man for allegedly planting pipe bombs outside the Democratic and Republican National Committees the night before the Jan. 6, 2021, Capitol riots — sensationally solving a major case that had deviled the bureau and languished under the Biden admin.

Brian Cole Jr., 30, was hauled from his $700,000 suburban home following months of investigative work in which the feds reexamined long-overlooked evidence in the five-year-old case, federal officials announced.

“Today’s arrest happened because the Trump administration has made this case a priority. The total lack of movement in this case in our nation’s capital undermined the public trust of our enforcement agencies,” Attorney General Pam Bondi said.

Cole was charged with transporting explosives across state lines with intent to kill, injure and cause damage and attempted malicious destruction by means of explosive materials.

The case remains under investigation, Bondi said, adding that more search warrants are being carried out — with additional charges possible as the case progresses.

“This is what it looks like when you work for a president who tells you to go get the bad guys and stop focusing on other extraneous things not related to law enforcement,” said Bongino, who has made the case a priority since taking office in March.

“You’re not going to walk into our capital city, put down explosive devices and walk off in the sunset. We were gonna track this person to the end of the earth. There was no way he was getting away.”

Surveillance footage from the night of Jan 5, 2021, captured a hooded figure wearing a mask, gloves, glasses, and Nike Air Max Speed Turf sneakers, carrying a backpack and planting what investigators deemed “viable explosive devices” at the two major party headquarters in Washington, DC.

The bombs were discovered the following afternoon — around the same time Congress convened to certify the 2020 electoral votes and enraged Trump supporters stormed the House and Senate chambers.

A seemingly docile Cole assembled his crude explosive devices from items purchased at several retailers around northern Virginia, including eight different Home Depots, as well as Micro Center, Lowes and Walmart, according to the federal complaint.

The pipe-bombs were fashioned from eight-inch galvanized steel pipes closed off with ends caps, and rigged with nine-volt batteries and white kitchen items, the feds alleged.

Authorities said he began building his intended fatal weapons in the fall of 2019, purchasing electrical wire, battery connectors, and explosive caps from the local shops. And throughout 2020, he added steel wool, end caps, and galvanized pipe to his would-be lethal arsenal, according to the complaint.

Bondi stressed that the breakthrough came from “good, diligent police work and prosecutorial work,” carried out by the FBI, ATF, Capitol Police, DC Metropolitan Police, and the DC US Attorney’s Office.

Patel, who also blasted Biden for letting the case go dormant, said that under Bongino’s leadership, the bureau enlisted a new team of investigators and experts to reexamine all the evidence and comb forensic data, leading to numerous leads and search warrants.

He noted that investigators sifted through “three million lines” of cellphone data and charging documents indicated cell tower data placed Cole near Capitol Hill when the devices were planted.

Authorities believe one pipe bomb was placed at the DNC around 7:54 p.m. and at the RNC at 8:16 p.m.

“When you develop evidence, you get a search warrant,” Patel said, adding that it was work the Biden administration “refused and failed” to act on.

“When you get a search warrant, you get an address. When you get an address, you hit the house, and that’s what we did.”

Federal agents swarmed the Coles’ home following the critical discovery that has vexed and embarrassed the bureau for nearly five years.

Neighbors living near the suburban cul-de-sac described a young man who shunned most human interaction and doted on a pet Chihuahua.

“He’s very antisocial. Very,” a woman who said she had lived in the neighborhood since 1991 told The Post of Cole. “He keeps to himself.”

“He has a dog that he loves,” she added. “He walks every day, twice a day, to 7-Eleven with his dog and he wears his headphones.”

“He seemed very quiet. He would never make eye contact. Almost like he just didn’t see you,” added a second neighbor, a man who noted that Cole would “wear shorts all winter long, and red Crocs.”

“I’m pretty shocked,” said this neighbor, who lived in the area for seven years. “This is a very uncommonly friendly and neighborly place to live.”

The second neighbor said he doubted that Cole was the person recorded planting the bombs, claiming Cole has “uncommonly short legs” and a simple “gait analysis” could rule him out or “confirm” him as the culprit.

Cole’s arrest comes one month before the fifth anniversary of the melee that briefly delayed congressional confirmation of Biden’s election victory.

“Today begins the formal process of accountability, where the defendant will begin his journey through the criminal justice system,” DC US Attorney Jeanine Pirro told reporters.

“And I pledge to you that the United States Attorney’s Office will take it across the finish line.”
