WASHINGTON (AP)  Federal employees charged millions of dollars for Internet dating, tailor-made suits, lingerie, lavish dinners and other questionable expenses to their government credit cards over 15 months, Congressional auditors say.

A report by the Government Accountability Office, obtained Tuesday by The Associated Press, examined spending controls across the federal government in 2005 and 2006 after reports of credit-card abuse at some departments.

The review found that nearly 41 percent of roughly $14 billion in purchases  legitimate or questionable  did not follow procedure, because they were unauthorized or improperly received.

In a sample of purchases totaling $2.7 million, the government could not account for hundreds of computers, iPods and cameras worth more than $1.8 million. The Army could not locate computer items making up 16 server configurations, each of which cost nearly $100,000.
