Excerpt:
Authorities intercepted a parcel this morning addressed to Rep. Peter King (R-N.Y.) containing a bloody pig's foot and a derogatory message, a source has confirmed to CBS News.
The parcel was intercepted at the Congressional mail facility in Landover, Maryland, where mail sent to lawmakers is screened for security risks.
The U.S. Capitol Police and U.S. Postal Service confirmed that there is an open investigation, though would not confirm the details of what was contained in the parcel because the investigation is ongoing. King's office, which did not see the parcel, referred all questions to the Capitol Police.
