In anticipation of Republicans filibustering a cloture vote late Monday, Sens. Chuck Schumer (D-NY) and Sheldon Whitehouse (D-RI) vowed to continue pushing the "Buffett Rule" until it passes.
"We're going to come back to this issue repeatedly," said Schumer, the No. 3 Democrat. "If you keep at these issues … as pressure mounts on the other side, they often are willing to go along. And that gets truer as you get closer and closer to election day."
Whitehouse, the sponsor of the legislation, said he'll "work hard" to make sure the principle -- which requires people making above $1 million per year pay at least 30 percent in taxes -- makes it into any tax reform legislation Congress takes up.
