President Obama has signed into law a measure critics say guts key transparency provisions from a law designed to combat insider trading by members of Congress. The new bill repeals a requirement in the Stop Trading on Congressional Knowledge Act that high-level federal officials disclose financial information online. But, according to the Center for Responsive Politics, it also removes requirements for the searchable and electronic filing of information related to potential conflicts of interest by the president, vice president, Congress and other officials. On its website OpenSecrets.org, the Center wrote: “Without the provisions, the STOCK act is made toothless. Insider trading by members of Congress and federal employees is still prohibited, but the ability of watchdog groups to verify that Congress is following its own rules is severely limited because these records could still be filed on paper — an unacceptably outdated practice that limits the public’s access.”
