For 12 years, Sen. Jeff Merkley (D-OR) has pushed for a ban on congressional stock trading, calling the practice “corrupt,” “unacceptable” and “wrong.”

Now, Merkley is confident an amended version of the Ending Trading and Holdings in Congressional Stocks (ETHICS) Act has enough bipartisan support that it will come out of a markup meeting with the Senate Committee on Homeland Security and Governmental Affairs on Wednesday with the votes necessary to present the amendment for a vote.
