Kent Walker, Google vice president and general counsel, testifies during a U.S. Senate Intelligence Committee hearing looking into Russian meddling in the 2016 U.S. elections via the use of social media, on Nov. 1, 2017.

Wednesday morning, two of tech's biggest names, Twitter CEO Jack Dorsey and Facebook COO Sheryl Sandberg, will testify in front of the Senate Intelligence Committee in a hearing on social media and foreign election interference.

But there's a notable absence. After a showdown over who would represent Google, it appears the committee's third invitee may not send anyone. The Mountain View, California-based company's pick, senior vice president of global affairs and CLO Kent Walker, was rejected by the committee last month because it was seeking a higher-ranking official.

On Tuesday, Walker published his testimony on Google's blog and said he would be submitting it, despite the rejection.

“Google is committed to working with Congress on these issues. In addition to providing private briefings, as our senior executive responsible for these issues, I will be in Washington briefing members of Congress on our work on this and other issues and answering any questions they have, and will be submitting this testimony,” Walker said in his written testimony.

In the testimony, Google's longtime GC laid out four steps the company has taken to reduce state-sponsored interference on its platform in the last 18 months, including: removing entities that mislead users about their identity, such as the Internet Research Agency, cybersecurity initiatives for elections and campaigns, verification programs for election ads in the U.S. and meeting with members of Congress.

“While the nature of our services and the way we run our advertising operations appears to have limited the amount of state-sponsored interference on our platforms, no system is perfect—and we are committed to taking continuing action to address the issue,” Walker said.

The committee's vice chairman, Sen. Mark Warner, tweeted Tuesday that Google parent company Alphabet's CEO Larry Page should fill the empty seat and testify. Chairman Sen. Richard Burr of North Carolina had told the Washington Post on Aug. 23 that he “wasn't accepting the senior vice president” from Google, seeking a CEO-level official.

“Tomorrow the Senate Intelligence Committee will hold an important hearing on the social media companies' responses to foreign influence operations. will be there. will be there. Larry Page should be there, too. It's not too late for to step up,” Warner, a Virginia Democrat and vice chairman of the committee, tweeted Tuesday.
