The father of accused D.C. pipe bomber Brian Cole Jr. was once defended by the civil rights attorney who represented George Floyd’s family, according to the New York Post.

"Ben Crump Law represented Brian Cole Sr. in late 2021 in a racial discrimination matter involving his Tennessee-based company, Free At Last Bail Bonding," Crump’s office told The Post.

"The engagement lasted less than a month."

Still, the firm has "never represented his son Brian Cole Jr. in any legal matter," Crump’s office said.

Cole Jr. was arrested Thursday for allegedly placing two pipe bombs outside the headquarters of the Republican and Democratic national parties in Washington on the eve of the U.S. Capitol attack, an abrupt breakthrough in an investigation that for years had flummoxed law enforcement and spawned conspiracy theories about Jan. 6, 2021.

The arrest marks the first time investigators have publicly identified a suspect in an act that has been an enduring mystery for nearly five years in the shadow of the violent Capitol insurrection.

Law enforcement officials reviewed credit card purchases of pipe bomb components, cellphone tower data and a license plate reader to zero in on Cole, according to an FBI affidavit filed in the case.

The FBI and Justice Department declined to elaborate on what led them to the suspect but characterized his arrest as the result of a reinvigorated investigation during the Trump administration and credited a fresh analysis of already-collected evidence and data.

Brian Cole Sr. hired Crump to represent him amid legal difficulties with his bail bonding company in Tennessee.
