WASHINGTON (MarketWatch) The House of Representatives voted overwhelmingly Thursday in favor of legislation to curtail insider trading of securities by lawmakers and officials in the executive branch, including a provision inspired by an alleged trade made by the husband of House Minority Leader Nancy Pelosi. The legislation seeks to prohibit lawmakers and their families and staffs from buying and selling securities based on their knowledge of nonpublic information. The vote follows passage of similar legislation in the Senate last week. The House voted 417 to 2 to pass the bill.
