CNN, with correspondent Kristen Holmes, is among the outlets reporting on the incident.

A 38-year-old man, Jeanine John Taele, was arrested in Downey, California after authorities found a gun in his car and ammunition on him while he appeared to monitor security at the Trump National Golf Course in Rancho Palos Verdes ahead of a fundraising event.

Federal investigators said they recovered a rifle, magazines, ammunition, body armor, and notebooks with concerning statements at Taele’s home, though officials have not released details about the statements.

Authorities note past assassination attempts against Trump and place Taele’s case within a broader context of security concerns surrounding the president and his events.

Officials stressed the case as an active security threat investigation and highlighted pre-visit security work intended to prevent any harm during the president’s fundraising schedule.

The investigation involves cooperation among federal and local agencies as authorities assess potential risks to the president and protected sites.

Trump commented to Fox News that only consequential presidents are targeted, a line he used to frame the security concerns around the event.

In related remarks, Trump downplayed the incident while shifting focus to other international topics, including Iran.

The report notes unsettling or ominous statements associated with Taele in the seized notebooks, though specifics were not disclosed.

Demonstrators from different sides gathered outside the fundraiser, underscoring ongoing political tensions around the event and presidential security.

Authorities described the situation as developing and said updates would continue as the investigation progresses.
