During the Republican National Convention, former President Donald Trump was heavily guarded by Secret Service agents as he arrived on the convention floor, in stark contrast to vice presidential candidate JD Vance who mingled freely with delegates. This heightened security came after a recent assassination attempt on Trump at a Pennsylvania rally, where a gunman fired from an adjacent roof, resulting in one death and injuries to two others, including Trump. The attack has prompted serious questions about the efficacy of the Secret Service and has led to increased protective measures for Trump and other political figures, including President Joe Biden and independent candidate Robert F. Kennedy Jr.

The Secret Service had already ramped up Trump's protection days before the attack due to an unrelated threat from Iran. Homeland Security Secretary Alejandro Mayorkas emphasized that additional protective resources, technology, and capabilities have been implemented, though specifics remain confidential. An intelligence bulletin from the FBI and Homeland Security warned of potential follow-on or retaliatory violence, highlighting that rallies and campaign events are likely to continue being targeted. The Trump campaign has also increased security around their offices and events, complicating Trump's usual interactions with supporters.

The assassination attempt and subsequent security measures have significantly impacted Trump's campaign dynamics. Regular interactions with supporters, such as signing autographs and posing for selfies, have become more challenging. Despite the increased security, Trump remains determined to continue his campaign activities, with his next rally scheduled in Grand Rapids, Michigan. The heightened security measures have also affected convention logistics, including disputes over protest zones, underscoring the ongoing tensions and challenges faced by the campaign in ensuring safety while maintaining public engagement.
