Lieberman: Arctic drilling a 'deal breaker'

He said allowing ANWR drilling "would be a deal breaker."

“That is just not going to happen,” Lieberman told reporters in the Capitol on Thursday.

Republicans have long called for drilling in the Arctic National Wildlife Refuge (ANWR). Lieberman's  comments come a day after Sen.

But Lieberman, who has championed efforts to keep ANWR permanently off-limits to drilling, said oil development in the Alaskan refuge won’t be in the mix.

“We are looking at a lot of things, we are bending to bring people in, but that one is a no-no,” he said.
