Cops investigating pig's foot sent to Rep. Peter King's office

From NBC's Luke Russert
A Capitol Hill source tells NBC that the Washington D.C. office of Rep. Peter King (R-N.Y.) was sent a bloody pig's foot with a note attached that contained anti-Semitic ramblings.

The note referenced King's controversial hearing last month about Muslim extremism within the United States.

The Capitol Hill police are treating this incident as an "open investigation."

The pig's foot was found when the package it was contained in was radiated and scanned for explosives. The package never actually reached King's office and was intercepted beforehand.
