Or you, but neither of us are the President of the United States.
And Twitter's "Terms of Service" predate the Trump administration.
If Trump doesn't want to follow the TOS and Twitter is required to let him do so with impunity, then what is even the point of having one?
So, just remember that Trump is not only above the law, he's even beyond a private company's Terms of Service and is not required to honor any contract or agreement, or pay any debt, or adhere to any oath.
Just remember that Trump may try to shut down YOUR private enterprise "if it displeases him".
Trump, the guy who supposedly represents those "small government conservatives".
