Andrew Weissman takes up the issue of the “interlocutory” appeal that all the lawyers are talking about regarding Trump’s alleged immunity from prosecution. It could have major implications for the election and he does a good job explaining it to non-lawyers: Last month, Judge Tanya Chutkan (correctly) rejected Trump’s motions to dismiss special counsel Jack Smith’s grand jury indictment on grounds including that he was immune from prosecution. In turn, Trump brought what’s known as an “interlocutory” appeal — meaning an immediate appeal before a final judgment in the lower court.
