The rare Republican rebellion Tuesday coincides with a notable shift to the left by Mr. Cuomo, who is advocating a minimum-wage increase and a package of women's rights laws this year in addition to the new firearms restrictions passed last month.
The package of tax proposals that Baucus has tacked on his amendments to the minimum wage bill also includes several other provisions, including a proposal to push back the date of taxation on corporate inversions to March 20, 2002.
