Markwayne Mullin representatives confirmed that death threats had been made against the freshman U.S. Congressman and family.
According to a press release from Karl Ahlgren, Mullin's chief-of-staff, authorities deemed the threats to be "a serious matter due to the content and nature of the threatening letters which were received."
Local and federal authorities have been notified and are investigating. Precautions have also been taken for the safety of Mullin and his family.
