Trump supporters trolled Bill de Blasio Monday during his presser at Trump Tower with signs that read, “Worst mayor ever” and “Trump 2020.”

The Communist Mayor of New York held a press conference at Trump Tower Monday to announce he will potentially hit the president’s real estate company with $2 million in fines if it doesn’t retrofit his buildings to comply with his Draconian “Green New Deal” building emissions standards by 2030.

Trump supporters heckled de Blasio, booed him and rode up and down the escalator with signs trolling him.

“Clearly the Trump Organization is a little sensitive to the fact that we’re calling them out for what they are doing to the climate but we are not backing down,” de Blasio said.

“We will take your money. We will hold you accountable,” the Communist added.
