The bipartisan energy efficiency bill that fell flat in May hits a nerve with Sen.

"I think that that piece of legislation has become a strong symbol of dysfunction," Heitkamp said during a policy dinner hosted by The Hill Monday.
"It is an important piece of energy legislation as a vehicle to have a discussion about other pieces, such as Keystone, such as fossil fuel development. Vote them up or down and let's just move on," Heitkamp said.
She added: "I will tell you though that it will go down for a lot of us as symbolic of what's wrong with the institution."
The failure to pass a piece of legislation that Heitkamp said has roughly 80 percent of the Senate behind it has generated "a lot of discussion" among lawmakers.
Still, the likelihood of the energy efficiency bill coming to the floor for a third time before November is slim.
