It’s unclear how the incident started.
“Late Monday, the United States Secret Service was informed that an agency employee working in Israel was allegedly involved in a physical encounter. The employee was briefly detained and questioned by Israeli police, who released him without charges. The employee has returned to the United States,” the Secret Service said in a statement. “In accordance with agency protocol, his access to Secret Service systems and facilities was suspended pending further investigation.”
CNN has reached out to the White House for comment.
