Washington (CNN) - Senate Republicans will filibuster any bill that doesn't extend Bush-era tax cuts to all income groups, Senate Republican Leader Mitch McConnell said Wednesday.
"The reality is that 42 Republican senators don't believe we should raise taxes on anybody, and there are also an indeterminate number of Democrats who agree with that," McConnell told CNN.
"You know how the Senate works," he said, referring to Senate rules that allow just 41 votes to filibuster legislation. "We're going to have an extension of all the current tax rates, the only issue is how long."
McConnell's comments came as talks were underway down the hall from his office between congressional Republicans and Democrats and White House officials about how to extend the Bush tax cuts.
It's no secret that this is the Senate Republican position on this issue, but for McConnell to be so blunt with demands even as bipartisan talks are underway suggests Republicans are not negotiating with flexibility.
Most Democrats are pushing for an extension of tax cuts just for families earning less that $250,000 a year although some have pushed to raise the threshold to $1 million. And as McConnell said, there are some Democrats who want extend all the tax cuts at least until the economy rebounds.
Earlier President Barack Obama spoke to reporters about the tax cut bill.
"I am confident that nobody wants to see taxes on middle-class families go up starting January 1st, and so there's going to be some lingering politics that have to work themselves out in all the caucuses, Democrat and Republican," Obama said. "But at the end of the day, I think that people of good will can come together."
