A Republican senator is holding up a popular bipartisan bill to crack down on cockfighting that was expected to pass easily in the Senate yesterday, drawing outrage from his congressional colleagues.

He added that Coburn has been known to put holds on any bill that he feels adds bureaucracy and cost to the federal government.
