(Reuters) – Facebook Inc (NASDAQ:) plans to highlight internal research that shows teenage girls felt better after using its Instagram app during a Senate hearing to be held on Thursday, according to the company’s prepared testimony seen by Reuters.

Since the Wall Street Journal’s report that Facebook knew Instagram could harm the mental health and well-being of its young users, social media giant Facebook has been in hot water.

Antigone Davis (global head of safety, Facebook) will discuss the company’s previous efforts to protect teens and children online. This includes defaulting Instagram users below 16 years old to their private accounts, as well as the previously stated measures to improve security.

U.S. Senator Richard Blumenthal announced the hearing titled “Protecting Kids Online” following the Journal’s reporting.

Davis prepared remarks reveal that 57% of teens who had felt sad in the past said Instagram helped them feel better.

The testimony showed that 51% of the teenage girls experiencing loneliness said Instagram had made their lives better.

At a Senate hearing, Blumenthal and MarshaBlackburn will present testimony from a Facebook whistleblower about Facebook and its safety measures for online children. Senators didn’t give details about the whistleblower.
