House Republicans backed away from their resolute position on the federal debt ceiling, announcing Friday that they will move this week to boost the government¡¯s borrowing authority for three months.

The move is a retreat from the earlier insistence among some Republicans that any such debt increase will have to be matched by spending cuts of equal or greater size.

A vote on the proposal is expected Wednesday. If successful, the measure will postpone what was expected to be a major clash with the White House over government spending.
