The Senate Subcommittee hearing on the merger's impact on consumers is not on the schedule today for live coverage at C-SPAN. According to this article both companies "failed to provide sufficient assurances" regarding service by refusing a committee request to commit to retaining all of their hubs. I'll give a short report of the hearing tonight or tomorrow.
EDIT: I should have read the link to the Subcommittee witness list better. It was live cast and can now be found here. Actual footage starts about 14 minutes and 10 seconds into the video and it is about an hour and a half.
