As Trump advocates for a federal campus security overhaul, the FBI reveals the motivation behind the shooting at Brown University.

The FBI said on Sunday that Ethan Harlow, 22, the shooter at Brown University, acted out of “deep-seated resentment toward the institution” following his expulsion for threats and harassment the previous semester.

During finals week, Harlow, who had posted manifestos online criticizing “elite indoctrination,” attacked the library, killing two undergraduates and injuring four before being neutralized by school police.

The Saturday Truth Social post by former President Donald Trump, in which he pledged “maximum justice” and denounced Brown’s leadership for “woke failures,” is still making waves.

On Monday, Trump announced a virtual town hall with Republican lawmakers and impacted families to promote the use of federal mandates to override state gun bans and arm trained campus guards.

Brown President Christina Paxson addressed the nation in a press conference, defending enhanced mental health protocols while rejecting Trump’s “politicization of grief.” “Our focus remains on healing,” she said, announcing a $10 million security fund. Vigils drew hundreds, blending calls for gun reform with prayers.

Democrats, including Sen. Jack Reed (D-RI), condemned Trump’s rhetoric as “exploitative,” while GOP figures like Sen. Ted Cruz echoed support for “proactive defenses.” The incident has reignited national debates, with polls showing 58% of voters favoring stricter campus vetting.

Investigation ongoing; Harlow bought his AR-15 legally in New Hampshire.
