INDIANAPOLIS (Reuters) - Democratic presidential candidate Barack Obama will push on Friday for passage of a bill to put the huge pay packages of some U.S. corporate executives under greater scrutiny.

The Illinois senator has introduced "say-on-pay" legislation that would give investors more of a voice in setting executive compensation packages.

"We've seen what happens when CEOs are paid for doing a job no matter how bad a job they're doing. We can't afford to postpone reform any longer," Obama said in prepared remarks for delivery later on Friday.

"That's why Washington needs to act immediately to pass this legislation."

Amid fears the U.S. economy may be in recession, many U.S. voters are anxious about a weakening job market, the mortgage crisis and higher gasoline prices.

At the same time, many are also expressing outrage over big pay packages given to executives of some of the companies at the center of the financial and mortgage crises, such as Bear Stearns Cos Inc and Countrywide Financial Corp."
