Does S in SEC stand for Sex...And why this story now?

While perusing the news today I saw an interesting article (http://www.msnbc.msn.com/id/36725550/ns/business-stocks_and_economy/) dealing with SEC employees surfing porn sites instead of doing their jobs. 
A study was done by SEC Inspector General David Kotz in response to a request from Senator Charles Grassley, R-Iowa.  It found among other things:

• A senior attorney at the SEC's Washington headquarters spent up to eight hours a day looking at and downloading pornography. When he ran out of hard drive space, he burned the files to CDs or DVDs, which he kept in boxes around his office. He agreed to resign, an earlier watchdog report said.
• An accountant was blocked more than 16,000 times in a month from visiting websites classified as "Sex" or "Pornography." Yet, he still managed to amass a collection of "very graphic" material on his hard drive by using Google images to bypass the SEC's internal filter, according to an earlier report from the inspector general. The accountant refused to testify in his defense and received a 14-day suspension.
• Seventeen of the employees were "at a senior level," earning salaries of up to $222,418.
• The number of cases jumped from two in 2007 to 16 in 2008. The cracks in the financial system emerged in mid-2007 and spread into full-blown panic by the fall of 2008.

While this is hardly news considering that the people working at SEC are just humans that are products of our society and its values I did find the timing of this quite interesting. The fact that it was asked for by a Senate Republican, albeit one who just voted against the GOP for Financial Regulation, is intriguing.  Knowing the history of Charles Grassley and his flip-flopping on Health Care (http://tpmdc.talkingpointsmemo.com/2010/03/grassley-look-how-great-this-health-care-bill-is.php) I wonder why he asked for the study at a time when SEC has filed a case against Goldman Sachs.  Could it be to embarrass the organization and switch the focus off of the suit? 

P.S. I did a bit of checking to see who Grassley's top donors were (http://www.opensecrets.org/politicians/summary.php?cycle=2010&cid=N00001758&type=C) and not surprisingly found them to be in Health, Insurance and Pharma industries.  That explains his stance on Health Care Reform.  Maybe it also explains his stance on Financial reform since I didn't see any large donations from that side.  We will see what happens when the full bill comes to the floor and track his contributions before that.
