I don't know if Graham said this, but Warner certainly did.
"But Sen. John Warner, R-Va., another of the 14, said the bipartisan group is "not trying to set ourselves up as some mini-structure" to challenge the two party's Senate leaders. Asked whether the Republicans who broke ranks with Frist should expect a backlash from conservative groups who had demanded the nuclear option, Warner said, "If you can't take the heat, get out of the kitchen."
Reid could hardly contain his excitement when he said that the nuclear option had been removed from the agenda."
