(WJW) — Facebook may be getting a makeover. The social media giant is planning a rebrand and new name, according to The Verge.

The news follows an hours-long outage and increased criticism from regulators about misinformation and content harmful to children.

Facebook CEO Mark Zuckerberg will talk about the name change during the company’s conference on Oct. 28, The Verge reports. The new name is reportedly a closely guarded secret.

Experts speculate this means a restructure for the company, and could mean changes to the other platforms it owns, including Instagram and WhatsApp.

News of the name change comes as the senator leading a probe of Facebook’s Instagram and its impact on young people is asking Facebook CEO Mark Zuckerberg to testify before the panel that has heard far-reaching criticisms from a former employee of the company.

Sen. Richard Blumenthal, D-Conn., who heads the Senate Commerce subcommittee on consumer protection, called in a sharply worded letter Wednesday for the Facebook founder to testify on Instagram’s effects on children.

“Parents across America are deeply disturbed by ongoing reports that Facebook knows that Instagram can cause destructive and lasting harms to many teens and children, especially to their mental health and wellbeing,” Blumenthal said in the letter addressed to Zuckerberg. “Those parents, and the twenty million teens that use your app, have a right to know the truth about the safety of Instagram.”

In the wake of former Facebook product manager Frances Haugen’s testimony early this month, Blumenthal told Zuckerberg, “Facebook representatives, including yourself, have doubled down on evasive answers, keeping hidden several reports on teen health, offering noncommittal and vague plans for action at an unspecified time down the road, and even turning to personal attacks on Ms. Haugen.”

Blumenthal did offer, however, that either Zuckerberg or the head of Instagram, Adam Mosseri, could appear before his committee.

“It is urgent and necessary for you or Mr. Adam Mosseri to testify to set the record straight and provide members of Congress and parents with a plan on how you are going to protect our kids,” he told Zuckerberg.

A spokesman for Facebook, based in Menlo Park, California, confirmed receipt of Blumenthal’s letter but declined any comment.

As public discomfort and scrutiny of the social network giant has grown in recent weeks, the focus has homed in on Zuckerberg, who controls more than 50% of Facebook’s voting shares.

Haugen, who buttressed her statements with tens of thousands of pages of internal research documents she secretly copied before leaving her job in the company’s civic integrity unit, accused Facebook of prioritizing profit over safety and being dishonest in its public fight against hate and misinformation.

“In the end, the buck stops with Mark,” Haugen said in her testimony. “There is no one currently holding Mark accountable but himself.”

On Tuesday, the attorney general of the District of Columbia added Zuckerberg as a defendant in a 2018 lawsuit he filed against Facebook on the privacy of users’ personal data. The action by Attorney General Karl Racine seeks to hold Zuckerberg personally liable in addition to Facebook in the case involving data-mining firm Cambridge Analytica, which gathered details on as many as 87 million Facebook users without their permission.

The Facebook users’ data is alleged to have been used to manipulate the 2016 presidential election.

“These allegations are as meritless today as they were more than three years ago, when the District filed its complaint. We will continue to defend ourselves vigorously and focus on the facts,” Facebook spokesman Andy Stone said.

Racine’s office said it was the first time a U.S. regulator specifically named Zuckerberg in a legal action. He and the company could face millions of dollars in penalties if violations of law were found.

The Federal Trade Commission has filed a major antitrust lawsuit against Facebook, and various state attorneys general also have taken legal action against the company.

“Based on the evidence we gathered in this case over the past two years … it’s clear Mr. Zuckerberg knowingly and actively participated in each decision that led to Cambridge Analytica’s mass collection of Facebook user data, and Facebook’s misrepresentations to users about how secure their data was,” Racine said in a statement. “The evidence further demonstrates that Mr. Zuckerberg also participated in misleading the public and government officials about Facebook’s role.”
