Michigan football head coach Jim Harbaugh has responded to the Order of Bulls Blood, the Rutgers secret society that vandalized Paramus Catholic HS before Wednesday's satellite camp.

Harbaugh took to Twitter to fire back:

History has documented many "secret orders" that have brought our country great shame. — Coach Harbaugh (@CoachJim4UM) June 9, 2016

Earlier Wednesday, the Order of Bulls Blood issue a statement to Harbaugh and Michigan, urging them to stay out of New Jersey, the state that has seen the Wolverines pull some of its top high school football talent in recent years.

Rutgers and its fanbase have been feuding for the last few months now. New head coach Chris Ash teamed up with Urban Meyer and former employer Ohio State for a satellite camp that was held on Wednesday evening in New Jersey, as well. Harbaugh is also set to speak at Paramus' commencement on Thursday evening.

Some thought the Wolverines ran the score up on the Scarlet Knights last season. They may do so even further if it comes to that during the matchup this fall.
