At least two more Democrats and a Republican senator failed to report stock transactions last year as a ban on congressional stock trading flounders in a Senate working group.
A new disclosure shows Rep. Kathy Manning (D-N.C.) and her spouse made dozens of undisclosed stock trades last year.
The bill, now stalling in the Senate, would require federal judges to report stock trades and make judges' financial disclosures available to the public online.
Researchers studying congressional stock ownership have found that the practice has effects on lobbying activity and potentially on market movements.
Senator and reps would no longer be able to bury their financial details on hand-written and poorly scanned paper filings.
