Elizabeth Warren: Congress will have 'blood on its hands' if it won't ban 'Rambo-style' weapons

Sen. Elizabeth Warren (D-MA) spoke up against what she called "the splintering of America" and partisan bickering as she took part in her party's filibuster for tighter gun safety laws on Wednesday.

"If we fail to act, the next time someone uses a gun to kill one of us, a gun that we could have kept out of the hands of the terrorists, the members of this Congress will have blood on our hands," she said.

As Politico reported, Warren's colleague Chris Murphy (D-CT) launched the filibuster with the goal of pushing through amendments on a spending bill that would institute universal background checks on gun purchases as well as a block on those types of purchases from anyone suspected of terrorism.

The filibuster is a response by Senate Democrats to the shooting massacre at an LGBT nightclub in Orlando, which resulted in the deaths of 49 people and injuries to more than 50 more.

"The FBI should have the authority to block gun sales to anyone they believe is a terrorist," Warren said. "If someone cannot get on an airplane because the FBI is concerned they might be plotting to do harm against Americans, then they shouldn't be able to walk into a store and buy a Rambo-style assault rifle."

The senator also argued that the homophobic nature of the attack should not be ignored.

"We are already beginning to see the splintering of America. One side shouts, 'It was a gun that killed all those people.' The other side shouts, 'It wasn't a gun, it was a terrorist that killed all those people,'" she said. "And through all of the shouting we miss what should be obvious: it was a terrorist with a gun that killed all those people. A terrorist with hate in his heart and a gun in his hand that killed all those people. It is time for us to acknowledge all of these truths and to come together to address them."
