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.
