Lieberman said he's "inclined" to include some of the elements of a compromise framework that Sens. Jon Kyl (R-Ariz.) and Sheldon Whitehouse (D-RI) have been working on for the critical infrastructure provisions in the bill, but no final decisions have been made.
"It's a big decision for us," Lieberman said. "They're still talking. I don't think they're going to reach an agreement with a lot of the people who are most concerned about the critical infrastructure part before the bill comes to the floor."
Lieberman believes including some components from the Whitehouse and Kyl compromise framework will help his bill get the votes needed to reach the magic number of 60.
"It's different than what we had. It's not as good as what we had, but it might be good enough to get us 60 votes to pass," Lieberman said of the framework. "It's something real, I think. In other words, it'll really have an effect in improving our security."
