In what’s become something of a ritual, members of Congress have lately been holding news conferences calling for stricter limits on their own stock trading. Time and again, in recent years, members of both parties have executed trades that seemed to be awfully well timed. In 2012, they passed the Stock Act to require that trades worth more than $1,000 be disclosed within 45 days. They could do worse than to endorse a bipartisan House proposal called the Restore Trust in Congress Act. It imposes a simple ban on individual stock trading by legislators and their immediate families, without loopholes for blind trusts or other complicated exceptions.
