Sen. Rand Paul (R-Ky.) ratcheted up his battle with New Jersey Gov. Chris Christie (R) on Monday night, accusing him of exploiting the victims of the Sept. 11, 2001 terrorist attacks.

Christie, meanwhile, responded on Tuesday by hitting Paul over the amount of federal aide his state receives.

And by the end of the day, Paul had labeled Christie the "king of bacon."

Christie said Thursday that he wants libertarian-leaning members of Congress who voted to defund the NSA's phone record collection program to explain their votes to the widows and orphans left by those attacks.

Paul suggested Monday that Christie is using the tragedy for political gain.

"It’s really, I think, kind of sad and cheap that he would use the cloak of 9/11 victims and say, 'Oh, I’m the only one who cares about these victims,'" Paul said on Fox News. "Hogwash. If he cared about protecting this country, maybe he wouldn't be in this, 'Gimme, gimme, gimme, gimme all the money you have in Washington -- or don't have.'"

Paul said people like Christie are "flippant" about privacy and the Bill of Rights.

"They do an injustice to our soldiers," Paul said. "Our soldiers are laying their lives on the line for the Bill of Rights."

Christie responded later Tuesday, saying he has "nothing personal against Sen. Paul."

Christie then pointed to the relative amount of federal funds that go to Kentucky and New Jersey and suggested Paul's state should return some of that funding.

"I find it interesting that Sen. Paul is accusing us of having a ‘gimme, gimme, gimme’ attitude towards federal spending when in fact New Jersey is a donor state and we get 61 cents back on every dollar we send to Washington," Christie said. "And interestingly, Kentucky gets $1.51 on every dollar they send to Washington. So if Sen. Paul wants to start looking at where he’s going to cut spending to afford defense, maybe he should start cutting the pork barrel spending that he brings home to Kentucky..."

Paul show back later Tuesday afternoon by calling Christie the "king of bacon."

"This is the king of bacon talking about bacon," Paul said, against referring to Christie's insistence that Congress pass the Hurricane Sandy relief bill.

He added: "What does he want to do, shut down military bases in Kentucky?"

Here are Christie's comments:
