Criticizing the BP oil spill was valid.
Criticizing a press that's biased and careless with facts IS valid too.
President Trump AND most of the 65 million people who voted for him understand that a free press is necessary for a free country and a safe world. Our complaint is about the quality of the work, the bias, the carelessness and the willingness to publish fake news.
Your Trump interview this morning that touched on the ongoing 'journalists pity party' with Trump and American is a case in point. It's no different than if BP was pretending people who objected to their carelessness that caused a large oil spill (destroying many Gulf ecosystems) was an attack on all energy companies... and NOT a valid complain about BP.
Trump's complaint that the way the press does their job is acting as the enemy of the people of United States is correct.
What ecosystems did the BP spill destroy specifically? The studies I found was the fishing boomed after the spill and there were no damaged beaches.
