the best advice is to just not watch ANY of the television news networks.....especially the ones that are on 24/7.
They have to fill the time with something so they repeat very often within an hour and any grain of sand information becomes a big rock within minutes.
They are in the business of making banquets out of ham sandwiches.
The best times we have is when we are on a cruise....no television.....very limited if any news....and who wants to spend time on that anyway.
No network or 24/7 news = the best Rx. If it should get bad enough you will find out soon enough. Restrict your news intake to TV happy paper
