WATCH: Senators unhappy by absence of Google executive

WASHINGTON — The Senate intelligence committee is holding a hearing on what it calls social media “influence operations” as the November elections near.

And while executives from Facebook and Twitter are testifying, there’s an empty chair in place for Google’s parent Alphabet, which has refused to send its top executive.

And committee leaders aren’t happy about that.

The committee chairman — Sen. Richard Burr — is praising the companies for what they’ve done so far. But the North Carolina Republican says threats from countries beyond Russia aren’t going away.

He notes that an outside security company had a large role in identifying the most recent threat the companies have disclosed. This was an attempt by Iran to meddle with politics using social media.
