Six major Web companies and internet-service providers, including AT&T Inc, Twitter Inc and Alphabet Inc’s Google, will detail their consumer data privacy practices to a U.S. Senate panel on Sept. 26, according to a congressional statement on Wednesday.

The Senate hearing will give the six technology-related companies, which also include Amazon.com Inc, Apple Inc and Charter Communications Inc, “an opportunity to explain their approaches to privacy,” said U.S. Senator John Thune, the Republican chairman of the Senate Commerce Committee.

They will also testify on “how they plan to address new requirements from the European Union and California, and what Congress can do to promote clear privacy expectations without hurting innovation,” Thune said.
