Donald Trump is a petulant president. Of that there can be no doubt.

The latest example of the president’s petty petulance reveals itself in the way he has reacted publicly to the deadly fires that are consuming hundreds of thousands of acres in California.

Would the president offer a highly public statement of support for the firefighters and other first responders? Or for the families that are being frightened by the fires or have lost all their possessions? Or the loved ones of the firemen who have died fighting to protect Californians?

Not yet, that I’ve heard.

He instead has issued a weird Twitter message in which he blames federal environmental rules that, according to Trump, have hampered firefighting efforts to quell the flames.

Trump lost California to Hillary Rodham Clinton in the 2016 election by roughly 4.3 million votes. He has been feuding with Democratic California Gov. Jerry Brown over environmental issues.

But the man who is president of all Americans — even those who oppose him — cannot yet bring himself to offer a soothing word of support for those who are suffering.

Disgraceful.
