Bush White House protecting Rep. Jerry Lewis

Scott Paltrow at the Wall Street Journal reports that the investigation of Rep. Jerry Lewis (R-CA) has been slowed by failure to fund the instigation. [H/T to Laura Rozen.]

This is another defense, following the bribe given to the U.S. Attorney Debra Yang who had been investigating Rep. Lewis. See

• Debra Yang was investigating Rep. Lewis, left to work for his law firm.

Question: Does Rep. Jerry Lewis know something that will further damage the Republican Party and/or the White House, or is this just the Republicans acting to defend one more Republican Congressman and his Congressional seat?
