I have been reading about this in places like the Guardian (UK) (Louisiana court halts criminal indictment against state attorney general) but could not understand what was happening.  I am going to copy an email from Senate candidate Jaime Davis which explains it better than the newspapers.

Besieged Louisiana Democrats are now headed into uncharted waters as Louisiana heads into what is now recognized as a full blown constitutional crisis.

In the month prior to MAGA’s unprecedented cancellation of the May 17th Elections in their state of emergency coup to remove Congressman Cleo Fields (D-LA), MAGA did something barbaric that received far less attention.

Calvin Duncan, a wrongly incarcerated Black survivor, won the election for Clerk of the New Orleans Criminal court on a mandate of reforming the system that took 30 years of his life. In response, our MAGA legislature passed a law to eliminate his office entirely rather than allow him to be sworn in this past May.

Democratic New Orleans Mayor Helena Moreno moved to correct the injustice by calling for a special election that would see Duncan’s victory restored. In retaliation, Louisiana’s MAGA Attorney General Liz Murrill, threatened to ‘take out’ Moreno in a coup.

Because of her coup threats, a grand jury in New Orleans has indicted Murrill on 16 felonies charges, her bond has been set at $400,000 USD, and an arrest warrant has been issued.

But Louisiana’s MAGA governor refuses to let her face justice. He has promised her a pardon if she is found guilty and has vowed to use the Louisiana State Police to defend her. On Friday his far-right State Supreme Court put a stay on the proceedings, however, in an exraordinary move, the special prosecutor in New Orleans has refused to remove the active warrant for Murrill’s arrest.

Louisiana is now in nothing short of a full blown constitutional crisis.

If the Attorney General steps foot in New Orleans she will be arrested by the New Orleans Police, but with the Louisiana State Police protecting her, what happens when they execute the warrant. How far could this escalate?
