I am sorry. Constant news would bug the heck out of me too. I understand

Since you work from home and need to have some peace and quiet and in addition you find constant news disturbing, your husband is welcome to watch the news on his tablet/laptop/phone with headphones on.

Absolutely not on TV that other person can see and hear.

If one of us wants to hear/see something and other person wants to do something else or find that stuff bothersome or not interesting or is working, then the other person does it with headphones on a private device. Then when we both up to watching something we both like to watch (and neither of us working), then we turn a tv in a common area and have it on tv and both watch. Other times tv stays off.

I don’t think you can stop him from watching news if he is obsessed with news (my dad is this way), but he must not do it in a common area with sound on.
