> Its important to add that Senators and Congressman are exempt of insider trading.

That's not correct. The STOCK Act, as noted in the Techdirt article you cited, prohibited members of Congress and many other government officials and employees from trading on non-public information for profit. This was enacted in 2012.

The STOCK Act was amended in 2013. The amendment changed the disclosure requirements for some government employees, but NOT for Congress. All of the STOCK Act prohibitions and reporting requirements remained in effect for Congress and remains in effect to this day.

In addition to Congress, the amendment also did not change anything for the President; the Vice President; people running for Congress; Deputy Secretary of Defense; Deputy Secretary of State; Deputy Secretary of State for Management and Resources; Administrator, Agency for International Development; Administrator of the National Aeronautics and Space Administration; Deputy Secretary of Veterans Affairs; Deputy Secretary of Homeland Security; Under Secretary of Homeland Security for Management; Deputy Secretary of the Treasury; Deputy Secretary of Transportation; Chairman, Nuclear Regulatory Commission; Chairman, Council of Economic Advisers; Director of the Office of Science and Technology; Director of the Central Intelligence Agency; Secretary of the Air Force; Secretary of the Army; Secretary of the Navy; Administrator, Federal Aviation Administration; Director of the National Science Foundation; Deputy Attorney General; Deputy Secretary of Energy; Deputy Secretary of Agriculture; Director of the Office of Personnel Management; Administrator, Federal Highway Administration; Administrator of the Environmental Protection Agency; Under Secretary of Defense for Acquisition, Technology, and Logistics; Deputy Secretary of Labor; Deputy Director of the Office of Management and Budget; Independent Members, Thrift Depositor Protection Oversight Board; Deputy Secretary of Health and Human Services; Deputy Secretary of the Interior; Deputy Secretary of Education; Deputy Secretary of Housing and Urban Development; Deputy Director for Management, Office of Management and Budget; Director of the Federal Housing Finance Agency; Deputy Commissioner of Social Security, Social Security Administration; Administrator of the Community Development Financial Institutions Fund; Deputy Director of National Drug Control Policy; Members, Board of Governors of the Federal Reserve System; The Under Secretary of Transportation for Security; Under Secretary of Transportation for Policy; Chief Executive Officer, Millennium Challenge Corporation; Principal Deputy Director of National Intelligence; Director of the National Counterterrorism Center; Director of the National Counter Proliferation Center; Administrator of the Federal Emergency Management Agency; Secretary of State; Secretary of the Treasury; Secretary of Defense; Attorney General; Secretary of the Interior; Secretary of Agriculture; Secretary of Commerce; Secretary of Labor; Secretary of Health and Human Services; Secretary of Housing and Urban Development; Secretary of Transportation; United States Trade Representative; Secretary of Energy; Secretary of Education; Secretary of Veterans Affairs; Secretary of Homeland Security; Director of the Office of Management and Budget; Commissioner of Social Security, Social Security Administration; Director of National Drug Control Policy; Chairman, Board of Governors of the Federal Reserve System; and Director of National Intelligence.

For other government employees, the change was that their required disclosures no longer had to be filed electronically or made available electronically. The disclosures are still available to the public, but on paper rather than online.
