Michael Bloomberg
President Trump's press office keeps shooting his message in the foot.
The billionaire is offering up his elite club of mayors to fight the president-elect's environment plans.
WHAT'S HAPPENING
The GOP nominee appeared to single out former New York Mayor Michael Bloomberg for special insults.
Michael Bloomberg tried hard to get under the skin of Donald Trump, and apparently succeeded brilliantly in irritating the less-successful billionaire.
The former New York mayor and Wall Street vet lampoons Trump's failures and warns he's a disaster.
The billionaire decided against running for president himself earlier this year.
"The astonishing thing about Mr Trump’s business career — given what he received — is not how much he has achieved but how little."
The CEO also says the future of Bloomberg political coverage, including "With All Due Respect," will be determined after the election.
