The Federal Trade Commission is investigating TikTok over its data and security practices, a probe that could lead to a settlement or a lawsuit against the company, according to a person familiar with the matter.

The investigation is the latest battle in Washington for the social media company, which is already fighting against a federal bill that could ban the platform in the U.S. if it doesn’t break ties with its Beijing-based parent company, ByteDance.

In its investigation, the FTC has been looking into whether TikTok violated a portion of federal law that prohibits “unfair and deceptive” business practices by denying that individuals in China had access to U.S. user data, said the person, who is not authorized to discuss the investigation.

The agency also is scrutinizing the company over potential violations of the Children’s Online Privacy Protection Act, which requires kid-oriented apps and websites to get parents’ consent before collecting personal information of children under 13.

NBC cuts ties with Ronna McDaniel

NBC News cut ties with former Republican National Committee chief Ronna McDaniel less than a week after hiring her as an on-air political contributor, a decision that followed a furious protest by some of its journalists and commentators.

In announcing the decision in a memo Tuesday, NBC Universal News Group Chairman Cesar Conde apologized to staff members who felt let down by the hire, acknowledging he had signed off on it.

There was no immediate comment from McDaniel, who stepped down as RNC leader just over two weeks ago. She found out she lost her job through media reports, not from NBC directly, said a person close to her who spoke on condition of anonymity because they were not authorized to speak about it publicly.
