Federal investigators examining the Trump assassination attempt are digging into the suspect's social media activity on Bluesky, searching for clues about his motive. Authorities believe Cole Tomas Allen may have posted on the platform under the handle "coldforce," promoting liberal views that did not stand out on the left-leaning platform.

Federal authorities searched a house connected to Allen in Torrance, California as part of the investigation. The focus on Bluesky represents a newer angle in domestic extremism investigations, as the platform has grown in popularity since the 2024 election cycle. Investigators are using open-source techniques to analyze the archive of posts.

The investigation highlights how platforms considered left-leaning can still harbor users with more extreme views. Investigators are working to determine whether the posts provide evidence of premeditation or ideological motivation behind the assassination attempt.
