Equifax shares are tumbling after Senator Mark Warner (D-Va) asked the Federal Trade Commission to investigate the recent hack that impacted more than 143 million Americans, as well as the company's cybersecurity practices.
Shares of the credit company are down 7.53% on Wednesday after news of Senator Warner's request crossed the wires. They have fallen about 23% since news of the hack was first released released on Thursday.
The names and Social Security numbers for millions of Americans were hacked earlier this summer, but the hack wasn't disclosed until last week. Credit card numbers and other documents were also leaked, but for a smaller group of citizens.
Equifax shares are down 8.81% this year.
