That's all from me here on the west coast. This is a bit of what's been going on in US news and politics today:

Louisianna police say they plan to release all video associated with the death of Ronald Greene tonight. Green died after being pulled over and then stunned, kicked and dragged on the ground by state troopers in May 2019.

Originally police told Greene's family that he died from the impact of crashing his car into a tree, but a 46-minute video obtained by the AP shows completely contradicts the police's version of events.

The 46-minute clip shows one trooper wrestling Greene to the ground, putting him in a chokehold and punching him in the face while another can be heard calling him a stupid motherfucker".

Greene wails I'm sorry!" as another trooper delivers another stun gun shock to his backside. Another trooper can be seen briefly dragging the man face down after his legs had been shackled and his hands cuffed behind him.

Two years ago, Louisiana State Police said Ronald Greene was killed in a car crash.

They lied.

Bodycam footage just released to the public clearly shows Greene was tortured to death by officers who denied him life-saving aid.https://t.co/G1qhrjXBLv
