A growing group of Senate Democrats are opposing President Obama's plan to let taxes go up on high income Americans.

The Hill reports that at least seven Democratic senators, including Sens. Jon Tester, D-Mont., and Joe Manchin, D-W.Va., may support an extension of the Bush tax cuts.

The lawmakers say they don't want to raise taxes on anyone in a weak economy. They would break with party leaders who want to let taxes go up for people making a million dollars a year or more.

Tester said he'd prefer Congress pass a plan to cut spending and reform the tax code.

"I would much prefer dealing with the tax code, with all the expenditures, in a bigger package similar to the Simpson-Bowles [deficit reduction] proposal," The Hill quoted Tester.

"If we can do that and we can roll out a big package that is significant, then we can do something with the tax rate from a reforming-it standpoint and do some things that really get our deficit and debt under control," he said.
