WASHINGTON (Reuters) - Nearly all Republicans in the Senate signed a letter saying they will not vote for a Democratic plan to raise the debt limit in a sign that the measure does not have the support it needs to advance in Congress.
Forty-three of the chamber's 47 Republicans signed the letter, released on Saturday.
Democrats need at least seven Republican votes to clear a procedural vote in the 100-seat chamber. That vote is scheduled for 1 a.m. EDT on Sunday.
