“I hope we can work something out during the day, because it’s really unfair for him to hold up this extremely important piece of legislation,” said Reid on Friday morning.

On Wedneday night, Reid also warned votes are possible on Saturday and Sunday on further legislation. 

Coburn is filibustering the FEMA bill because he says it spends too much and ought to be offset with equal cuts in wasteful spending in other parts of the government’s budget.

The junior senator from Oklahoma also opposes parts of the Federal Aviation Administration and highway funding bill that Reid is expected to take up once FEMA has cleared the chamber. If that bill is not passed by Friday night, however, Reid says up to 80,000 workers could be out of work on Saturday morning.
