U.S. senators seek investigation of Equifax stock sales following data breach

WASHINGTON—More than one-third of U.S. senators want the Securities and Exchange Commission and the Department of Justice to get to the bottom of whether Equifax Inc. managers violated insider trading laws when they sold stock days after the company found out it was hacked.
Thirty-six lawmakers, consisting of mostly Democrats and some Republicans, signed letters sent to the agencies and the Federal Trade Commission Tuesday. The bipartisan request shows the degree of public outrage over a cyber breach that may have led to the theft of 143 million Americans’ personal data — and how it is reverberating in Washington.
