Bloomberg on Friday officially filed as a candidate for the Alabama Democratic presidential primary, signaling the first step in a possible White House run that could shake up the crowded primary field.

Amid speculation that Bloomberg would launch a presidential bid, Trump said Friday that he doesn’t think the former mayor would perform well in the primary. Trump added, however, that he’d like to run against Bloomberg, whom he nicknamed “little Michael.”

“Little Michael will fail. He’ll spend a lot of money. He’s got some really big issues, he’s got some personal problems and he’s got a lot of other problems,” Trump said. “He will not do very well and if he did, I would be happy. There’s nobody I’d rather run against than little Michael.”
