A security failure during an assassination attempt on Trump has led to intense scrutiny on the Secret Service. The failure prompted President Biden to order an independent review and House investigators to prioritize the issue. Questions arose on how the shooter was able to get close to Trump and why the Secret Service did not react promptly to remove Trump from danger. Criticisms include the lack of sufficient resources for protection and concerns about the Secret Service's commitment to diversity hiring impacting readiness. Despite praise for agents' protective actions, the delayed response and resource limitations have sparked widespread criticism and calls for an increase in Trump's security detail.
