The Senate is moving into its final phase of President Trump’s impeachment trial. The chamber will continue its debate over whether to call additional witnesses this afternoon and will move to vote on witnesses this evening. Here’s how the rest of the trial could play out:

If the Senate votes to call additional witnesses, such as former national security adviser John Bolton, the trial will likely extend into next week, and a final vote won’t occur until after the State of the Union address. Democrats would call on Bolton, and Republicans would almost certainly subpoena Hunter Biden and maybe even the anonymous whistleblower.
