Question

When a threat is made against the President of the United States or a successor to the Presidency, it is a violation of 18 USC 871. Who investigates this?

Answer 1

The United States Secret Service is responsible for investigating threats made against the President of the United States, covered under the violation of 18 USC 871.

Step-by-step explanation:

When a threat is made against the President of the United States or a successor to the Presidency, it is indeed a serious matter that falls under the violation of 18 USC 871. The primary agency that investigates such threats against the President and other protected officials is the United States Secret Service. The Secret Service has a dual role of both protection and investigation, especially in matters that involve the President and the integrity of the country’s financial infrastructure. Note that, while impeachment proceedings against a President for high crimes and misdemeanors are initiated by the House of Representatives and tried by the Senate, criminal threats are a separate matter handled by law enforcement, specifically the Secret Service.
