Sen. Elizabeth Warren (D-Mass.) Said Wednesday that she wants to extend proposals to ban stock trading between members of Congress to all state lawmakers, building on Washington’s growing momentum to handle the financial dealings of elected officials.

“Government officials must eliminate all conflicts of interest – whether at the federal or state level,” Warren told Business Insider on Wednesday. “It is also true whether we are talking about elected officials or current judges or members of the Federal Reserve. The public has a right to know that when people in power make decisions, they do so in order to advance the best interests of society, not to pursue their personal financial interests.

Her comments come a week after House Speaker Nancy Pelosi (D-California) said Democrat leaders were considering proposals that would ban members of Congress from trading in individual stocks, saying she expected legislation to be proposed “quite soon”. It was a surprising change of tone for Pelosi – one of the richest members of Congress – but this comes amid growing pressure from lawmakers on both sides of the aisle and concerned public that some in Washington have taken advantage of their positions.

“I believe in the integrity of people in the public service,” Pelosi said last week. “I want the public to have this understanding. We need to do this to prevent something that we see as a problem, but it is a matter of trust. And if that’s what the members want to do, then so will we. “

Ethics groups have found repeated violations of the 2012 Equities Act, which aims to combat insider trading, by lawmakers from both parties, and Pelosi herself said the law was not strong enough.

Several lawmakers, including Warren, have proposed restricting or banning stock trading. Last week, Warren introduced a bipartisan bill with Senators Debbie Stabenow (D-Mich.), Steve Danes (R-Mont.) And Marsha Blackburn (R-Tenn.) That would ban members of Congress and their spouses from owning or trading in individuals stocks. The bill provides for severe sanctions for violations.

Other proposals will simply require investments to be placed in blind trust or to exclude family members and spouses of legislators.

“Now is the time to tell the American people: You can be sure that when a representative or senator votes something, they do it because they believe in the country, not just for themselves financially,” Warren told CNN this week.
