The Times clearly supported Trump in 2016 by harping on Hillarys emails with daily articles and opinion pieces, just as it has spent the past year with articles and opinions that Biden is too old to be president. Bidens age has not been news for a long time, yet the Times chose to write news articles about it almost every day. That is propaganda, not news.
As for Tom Cottons piece, the Times got a lot of blowback from readers. This writer and others at the Times justified their decision to publish because Cotton was close to Trump and could be a presidential nominee at some point. With such logic, the Times would have agreed to publish an opinion by Goebbels that Hitler had a right to murder all Jews and Romany.
What Cotton was promoting was for Trump to send the US military to Democratic cities to prevent the protests against George Floyds murder. The excuse was that there had been some violence and looting even though most of the protests were peaceful and it was later learned that right-wing actors were instigating some of the violence. Cotton advocated breaking the Posse Comitatus Act, passed 1878 over concerns about using the federal military to enforce domestic laws. No news outlet should be giving a national platform to a politician to push the opinion that the President has a right to break the law, yet that is what the Times did.
Of course, now that the SC has said that presidents can violate most of our laws with impunity, all bets are off.
