Hawaii Reps. Colleen Hanabusa and Mazie Hirono are cosponsoring a bill that would ban members of Congress and other federal workers from using nonpublic information to make money in the stock market. 

They would also be prohibited from tipping off other people about what they know. 

Hirono said in a statement that it is “not acceptable” for members of Congress to make money off of “insider knowledge.”

Hanabusa and Hirono are among 273 members of the House who support the STOCK Act — short for Stop Trading on Congressional Knowledge Act.
