No the FBI's Steve D'Antuono actually told Congress the cellphone data was corrupted. And did you see very many people in the video around the bomber.
The Trump FBI was able to use the same cell phone data to identify the suspect. Then they searched the subject's credit card purchase history for purchases that were constant with bomb making materials. He started buying bomb making materials in 2019 BEFORE the election. The Trump FBI had the exact same evidence the Biden FBI had yet the Biden FBI could not find the bomber in 4 years.
