Donald Trump is a bully who is manifestly unfit for higher office, according to an attorney who claims to have represented the GOP nominee.

Trump is petulant, dishonest, lazy and ignorant, lawyer and businessman Thomas Wells explained in a lengthy editorial published by the Huffington Post.

"In 1987, when I was 35 years old and he was 41, Donald Trump hired me to be his attorney on a major northern New Jersey project, a shopping center, which like everything else, was to bear his name, Trump Centre," the attorney wrote.

He went on to explain that his limited contact with Trump was not an enjoyable experience, and that his main takeaway was that the casino tycoon relied heavily on bogus headlines and outright lies to maintain an air of success and importance.

"I have thought about this a lot, and I want to share my humble insights of why we cannot elect Donald Trump as president of the United States. To me, it is more about character than politics. Because of lack of the former, the latter ― the actual politics of Donald Trump ― are not that easy to discern," he added in a post titled "Donald Trump Hired Me As An Attorney. Please Don't Support Him For President."

Wells said he initially wanted to list only a few reasons for why Trump is unfit to be the next commander in chief. However, he added, once he started writing, he just kept going as he kept remembering additional reasons for why voters should turn away from Trump.

Wells said he eventually forced himself to stop at 20.

Here are just a few of the reasons listed by the former Trump attorney:

1. The man lies all the time.
Like the skilled liar he is, he does it with impunity. "I watched in Jersey City, NJ when thousands and thousands of people were cheering as the World Trade Center collapsed." "The last quarter the gross domestic product was less than zero." "The number of illegal immigrants in the United States is 30 million, it could be 34 million." "The Mexican government forces bad people into our country." "The unemployment rate may be as high as 42 percent."
All these things have been said by Donald, actually often yelled by him, and many times over and over in front of large crowds. How about the whopper, "Crime statistics show blacks kill 81 percent of white homicide victims"? One has to wonder why this lie would be conceived, much less told. Donald Trump says all of these things forcefully, so they must be true. But they are not!
Unambiguously, they are what is described as "pants on fire" untruthful, as in, not a shred of truth. In passing, you have to ponder whether yet another of Donald Trump's oft made statements about the fervor of his Christianity and the Bible being his favorite book are also not grounded in truth. Clearly, "thou shall not lie" is not his favorite of the Ten Commandments.
2. It is actually not all about the candidate.
"It's amazing how often I am right?" "I alone can fix this." "I have a big brain." "I advise myself." "I am very, very rich."
Donald really said all these things. His ego seems to know no bounds. When Donald feels insulted by someone, he obsesses without control. He fusses, he fumes, and he says unbelievably inappropriate things. He is in his glory when he can bully his way to a result he covets.
Did you ever notice that those real people stories other candidates are always telling about someone they just met, struggling with a difficult problem, are just not in the Trump lexicon? He keeps telling us he is all about winners. I guess these folks don't qualify. Said another way, Donald Trump doesn't play well in the sandbox with others.
First, he has his own ideas as to who can be in the sandbox with him. He also wants to run the sandbox. He is the kid who gets his way or stomps off in a huff. What happens when he figures out, even our nation's highest office is not all about him? Do we want him with the codes to nuclear weapons?
3. U.S. presidents are by design not kings.
The Constitution makes them share power. Donald Trump who uses the "I" word more than anyone who has ever aspired to the job, has a brazenly authoritarian bent. He wants to be a "strongman," not a president.
One has to wonder what would happen if he actually had to govern or make one of his deals in a zero sum world of politics where the other side just says no. What then of his notoriously short attention span, temper or non-stop need to tweet his every frustration?

These are just three of his twenty reasons.
