WASHINGTON (AP) — 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.
