The President receives about 500 death threats every month!
Whether that figure is higher or lower than you expected, it still poses a huge responsibility for those guarding him. The Secret Service gained it's protective responsibility in 1901 after President McKinley was assassinated. It used to protect presidents for life, yet in 1997, this perk was altered to only 10 years after leaving office.
In 2010, the Secret Service had more than 1300 members who provide security for the White House, the Vice President, the Treasury, and diplomats in DC. Because the President is the most powerful man in the free world, the Secret Service makes constant efforts to ensure that those 500 threats each month don’t happen. Threatening the President is a class D felony and can result in 10 years in prison!
