Will resolve N/A if Trump does not assume office of the presidency.
If, while Trump is in office, Vance either quits or is impeached/fired this resolves yes. If Vance dies, or assumes the presidency, or completes his VP term this resolves no.
What are you imagining "fired" to involve? Impeached in general? Impeached at Trump's specific urging? Told not to run again (Trump can't anyhow)? Systematically excluded from power except for any of the few instances of hard power the VP has? Explicitly asked to resign?
It's an elected position, you can't just fire people from it!
@SeekingEternity I’d describe it as a successful attempt by Trump to push Vance out of the VP position, this includes a Trump-supported impeachment or Trump asking Vance to resign
