"Can trump fire Jack Smith if he is elected?
Possible but unlikely. Legal advisers would probably tell Trump not to do so, as they did during the Mueller crisis.
If Trump ignored their views, he could face an impeachment hearing in the
Senate and some
Republican Senators might vote against him.
However, Trump has been through two impeachment attempts before, including one after Mueller published his report. It's possible that Trump may try to ride out the storm and fire Jack Smith.
It's possible he may decide it's not worth it. As it stands now, one of his two federal cases has been dismissed. The one remaining case, the electoral fraud indictment in Washington, D.C, has been greatly neutered by the
Supreme Court's July 1 ruling on presidential immunity.
In addition, the Justice Department has written instructions not to prosecute a sitting president. Trump would not face a trial until he had left office."
