Jordan, who is ranking member of the House Judiciary Committee, said he sent a letter to FBI Director Christopher Wray on March 9 after a senior FBI special agent came forward with information regarding an "unusual" request from the FBI's Washington Field Office.

"According to the special agent, on February 7, 2022—over a year after the placement of the bombs—the FBI's Washington Field Office asked FBI field offices to canvass all confidential human sources nationwide for information about the individual and the crime," Jordan said in his letter.

"In part, the message asked that the canvass 'include sources reporting on all [types of] threats' because the suspect's 'motive and ideology remain unknown.'"

Jordan said that the special agent had described the request as "unusual" because it "was transmitted more than a year after the FBI had begun the investigation, and it raises questions about the progress and extent of the FBI's investigation."
