Senate may subpoena Facebook's Mark Zuckerberg, Google's Sundar Pichai, Twitter's Jack Dorsey to testify

The Senate Commerce Committee on Thursday authorized subpoenas for Facebook CEO Mark Zuckerberg, Sundar Pichai of Google, and Twitter's Jack Dorsey.

Sen. Roger Wicker [R-MS], who heads the committee, today said testimony of the three social media CEOs testimony is needed "to reveal the extent of influence that their companies have over American speech during a critical time in our democratic process."

The committee's unanimous vote marked the start of a new bipartisan initiative against Big Tech companies, which have been under increasing scrutiny in Washington and from state attorneys general over issues of competition, consumer privacy and hate speech.

Facebook, meanwhile, is expanding restrictions on political advertising, including new bans on messages claiming widespread voter fraud. The new prohibitions laid out in a blog post come days after President Donald Trump raised the prospect of mass fraud in the vote-by-mail process during a debate with Democratic rival Joe Biden.

A new review by The Associated Press found that Facebook and Twitter still aren't enforcing even the limited restrictions they've recently put in place to stem the tide of dangerous material from QAnon, with an audience of millions on their platforms. The two companies had promised to stop encouraging the growth of the baseless conspiracy theory, which fashions Trump as a secret warrior against a supposed child-trafficking ring run by celebrities and government officials.
