Thomas Matthew Crooks used the alias 'Bob Dole' for online purchases in the months before he opened fire at Donald Trump's July 2024 rally in Butler, Pennsylvania, according to federal records reviewed by US news organisations, with packages sent to his parents' home under the pseudonym.
The documents add detail to Crooks' online activity before the attempted assassination, but do not establish why he chose the name or whether every purchase was linked to the attack. They also do not provide a definitive motive for the shooting.
