Alphabet’s decision to decline to send its CEO Larry Page to today’s Senate Intelligence Committee hearing — to answer questions about what social media platforms are doing to thwart foreign influence operations intended to sow political division in the U.S. — has earned it a stinging rebuke from the committee’s vice chair, Sen. Mark Warner.

“I’m deeply disappointed that Google – one of the most influential digital platforms in the world – chose not to send its own top corporate leadership to engage this committee,” said Warner in his opening remarks, after praising Facebook and Twitter for agreeing to send their COO and CEO respectively.
