Liberals in Congress are whipping votes to beat back Rep. Bart Stupak's (D-Mich.) abortion amendment, Rep. Jan Schakowsky (D-Ill.) said this morning.

"We're going to be organizing today to vote against the amendment," Schakowsky told C-SPAN's Washington Journal.

Stupak's amendment explicitly bars federal subsidies from going to plans that cover abortion. The Rules Committee agreed last night to allow an up or down vote on Stupak's amendment.

The Illinois Democrat said she'll vote for passage today regardless of whether Stupak's amendment is included, but would oppose a final bill if the amendment makes it through conference committe.

"If that language were in the final final bill, I certainly couldn't support it," Schakowsky said.
