The US Secret Service is a federal law enforcement agency under the Department of Homeland Security, charged with conducting criminal investigations and protecting the President and Vice President. The protection for the current and former Presidents and their families, including Donald Trump, as well as Vice Presidents such as Kamala Harris, is an important aspect of their work. This move to boost protection could be due to a number of reasons, such as an increase in perceived threats, specific events or situations demanding a higher degree of security, or it could be a routine update in their protection measures. The details of these security measures are highly confidential. However they include measures such as physical protection, surveillance, and emergency response. Both Harris and Trump would be provided with round-the-clock personal protection in addition to other measures designed to ensure their safety.
