Democrat presidential candidate Mike Bloomberg is reportedly “fuming” over President Donald Trump’s attacks on his height and is preparing to enact his revenge against the president for the attacks.

Trump, who has repeatedly referred to Bloomberg as “mini Mike,” hit the former New York City mayor hard during a Fox News interview that aired during the Super Bowl pre-game show when asked by Sean Hannity what the first thing was that came to his mind when it came to each of the top Democrat presidential candidates.

When Trump was asked about Bloomberg, he said, “Uh, very little. I just think of little. You know, now he wants a box for the debates to stand on. Okay, it’s okay, there’s nothing wrong. You can be short. Why should he get a box to stand on, okay? He wants a box for the debates. Why should he be entitled to that? Really. Does that mean everyone else gets a box?”

FOX Business Senior Correspondent Charles Gasparino reported on Sunday that Bloomberg was furious over the insult and appears to have already planned out how to hit back at the president.

Gasparino tweeted: “SCOOP-inside the @MikeBloomberg campaign advisers say Bloomy is fuming over @realDonaldTrump’s attacks, mocking of his height. BBG now says he will fund even @BernieSanders to beat Trump. He plans to ramp up the personal attacks vs Trump through even more pointed TV ads”

While Trump and Bloomberg are both billionaires, Bloomberg reportedly has much deeper pockets than Trump does as he is worth $60.2 billion compared to Trump’s estimated $3.1 billion net worth.

Bloomberg’s wealth is already becoming a problem in the race as his Democrat rivals struggle to keep up with the amount of money that he is spending in advertisements, which also attack Trump.

“To date, Bloomberg has dished out a massive $248 million to run commercials since declaring his candidacy for president in late November, according to the latest data from the ad-tracking firm Advertising Analytics,” Fox News reported. “By comparison, no other candidate in the Democratic presidential primary field has topped $30 million in spending.”

Advertising Analytics account manager Ben Taber told Fox News: “Bloomberg’s buy is truly unprecedented. For context, the Clinton campaign in 2016 spent $230 million throughout the course of the entire election, including the general. Bloomberg has spent more than that since November 25th. This cycle, Bloomberg has spent three times more than Sanders, Warren, Buttigieg, and Biden, combined.”
