Senate Confirms Trump's Pick for NSA, Cyber Command (politico.com)
An anonymous reader shares a report: The Senate Tuesday quietly confirmed President Donald Trump's nominee to lead the National Security Agency and U.S. Cyber Command. U.S. Army Cyber Command chief Lt. Gen. Paul Nakasone was unanimously confirmed by voice vote to serve as the "dual-hat" leader of both organizations. The two have shared a leader since the Pentagon established Cyber Command in 2009. He will replace retiring Navy Adm. Mike Rogers after a nearly four-year term. The Senate Intelligence and Armed Services committees both previously approved Nakasone's nomination by voice vote.
So that just means we don't get to know who voted for this guy, or even if there were enough votes for him to carry.
No, it means the guy was confirmed overwhelmingly (the article states it was unanimous). Congress will do voice votes when there's no serious opposition to the matter at hand. If a Senator didn't like him, that Senator could have raised an objection and forced a on-the-record vote. That didn't happen, so you can assume that everyone present in Senate was fine with him.
