WASHINGTON - Legislation to prevent the government from going over the so-called fiscal cliff will also block a $900 automatic pay hike for members of Congress.

It's one more reason for lawmakers to vote for the measure extending Bush-era tax cuts on individual income up to $450,000 while increasing rates for earnings above that threshold.

Under a 1989 law, lawmakers are supposed to receive automatic cost-of-living pay hikes, but as Congress' approval ratings have fallen, lawmakers have routinely voted to reject the raise.

Lawmakers make $174,000 a year. They had already voted in September to block the pay raise through March 27, but President Barack Obama recently issued an executive order to implement it, along with a pay increase for federal workers.
