Donald Trump has again demonstrated that he is not only unfit but dangerous to be president. He and his corrupted Justice Department under Attorney General William Barr has abused the antitrust laws by challenging an effort by California and major automobile manufacturers to reduce greenhouse gases by agreeing to reduce auto emissions voluntarily.

By agreeing to improve engine efficiency to 51 miles per gallon by 2026, close to the 54.5 MPG by 2025 proposed by President Barack Obama, but higher that the 37 MPG required by Trump, they have offended the president.

Trump would needlessly require automakers to do less for the environment to fight global warming even though they are willing to do more. And because they have, by doing so, disagreed with his resistance to fight global warming, he has ordered the full power of the taxpayer-funded Department of Justice to punish them.

Trump again has put his ego and pride above the welfare of Americans — indeed, the world — and shamelessly displayed his narcissistic personality disorder. He is a real danger to humankind.
