Senate quietly easing restrictions on their own insider trading, to protect "national security"

I wish I could express surprise. I can, however, muster some dismay:

The Senate has severely scaled back the Stock Act, the law to stop members of Congress and their staff from trading on insider information, in an under-the-radar vote that has been sharply criticised by advocates of political transparency. 

The changes, if they become law, will exclude Congressional and White House staff members from having to post details of their shareholdings online. They will also make online filing optional for the president, vice-president, members of Congress and congressional candidates. 

The House was expected to pass a similar bill on Friday.

MR posts links to the FT article, other sources, and says "Some officials suggested that transparency "could threaten national security," more detail on that here.  Here are some further interesting details."

Clearly, what we least need right now from our elected leaders is an assurance that we will know less and less about their business and financial dealings while they ostensibly serve in the public interest. For shame.
