I have ROKU and you cannot get FOX News live on ROKU except paying for Hulu live. You might get in through You Tube. Not sure though.
Yes, you can get in via You Tube.
One of the ways is to do a search in You Tube for Gramp’s Live.
There’s another one, JuJu Bot.
I seem to have hit and miss days but noticed that the Gramp’s site comes on in the early evening and I can watch it thru mid-morning the following day if I chose to.
