If McConnell lacks the votes, then which witnesses might we hear from?

The Senate’s opening arguments have now concluded, which means the next step is a vote on whether to call impeachment trial witnesses. As of right now, it looks like a majority of senators will vote in favor of additional testimony.

Senate Majority Leader Mitch McConnell reportedly told his party this week he didn’t have the votes to block the Democrats from subpoenaing former national security adviser John Bolton or acting chief of staff Mick Mulvaney. Bolton has already agreed to testify if asked, and Mulvaney will almost certainly reject the Senate’s subpoena and cite executive privilege. This means we could hear from Bolton as soon as next week.
