U.S. Sen. Charles Grassley, R-Iowa, shot back Friday in a battle over the propriety of bonuses for employees of government-backed housing financiers Fannie Mae (FNM) and Freddie MAC (FRE), telling CNBC that scrapping the extra pay would help steer corporate America toward a needed overhaul.

James Lockhart, director of the Federal Housing Finance Agency, which regulates Fannie and Freddie, said in a letter to Grassley this week that the bonuses, totaling $210 million, were justified. About $51 million was paid out in late 2008 with the rest to be disbursed this year and early in 2010. A total of about 7,600 employees are affected, with a maximum for any single bonus of $1.5 million, according to a copy of the letter obtained by The Wall Street Journal.

But Grassley isn't buying Lockhart's argument that the bonuses are needed to entice Fannie and Freddie employees not to quit their jobs at a time when their expertise is needed to help the troubled firms unwind their money-losing positions.

"It doesn't matter what I think or what Mr. Lockhart said," Grassley told CNBC. "We have high unemployment. ... Are you going to lose all the people? I don't think so."

Still, the Republican senator thanked Lockhart - an appointee of former president George W. Bush - "for being transparent and getting the information out."

The larger issue, he stressed, is that taxpayers are outraged their money is being used to enrich people at companies whose failures helped cause the economic crisis.

"I'm trying to change the corporate structure of America so we feel a little bit of remorse and hear a little bit of apologies for the way these leaders have run these corporations into the ground. And I've not heard that yet."
