The U-S Senate has rejected a bipartisan compromise that would have expanded background checks on gun purchases. Republican US Senator Pat Toomey remains hopeful that the background check compromise, which he brokered, can earn 60-votes. Toomey says a background check expansion is not gun control -- it's common sense. The Toomey / Manchin amendment includes specific language barring the creation of a federal gun registry. Toomey says he is not worried about backlash from the gun lobby.
