Senator Josh Hawley introduced the Preventing Elected Leaders from Owning Securities and Investments Act in an effort to once again stop lawmakers from trading in stocks.

“Members of Congress and their spouses shouldn’t be using their position to get rich on the stock market,” Hawley tweeted in announcing his bill.

Last year former speaker, Nancy Pelosi’s husband, Paul Pelosi, sold millions of dollars worth of shares of a computer chipmaker – just as the House prepared to vote on a bill focused on domestic chip manufacturing.

A spokesperson for Pelosi said he had sold the shares at a loss.
