A U.S. House panel said Wednesday the chief executive of Equifax will testify about a massive data breach that impacted up to 143 million Americans at an Oct. 3 hearing, as the company's shares fell another 14.6 percent amid pressure on the company to explain its handling of the hack.

The company's shares have fallen more than 30 percent this week amid letters from members of Congress about the hack and requests for answers.
