Trading stocks by members of Congress has been the subject of scrutiny and criticism over the years, prompting questions about whether lawmakers leverage access to privileged information to get an edge on markets.
"It's clear the current rules are not working," the lawmakers wrote, citing several high-profile cases of senators making significant stock sales after receiving closed briefings on the COVID-19 outbreak in the early days of the pandemic in 2020, before the general public had understood its implications for markets.
Members of Congress were elected to "serve our country, not turn a quick a buck," they wrote, arguing that a law barring lawmakers from owning or trading stocks while in office would help restore public trust.
