Donald Trump has another ax to grind in his quest for the White House, this time with Mike Bloomberg.

The controversial presidential candidate took a shot at the former mayor in an interview with the Daily Mail Wednesday after a Bloomberg News article stated Trump's net worth was "only" $2.9 billion.

The real estate mogul, who claims he's worth $10 billion, said the report was fueled by jealousy since Bloomberg "always wanted to do what I'm doing," and the news organization treated him "more dishonestly than probably any other outlet."

"I think they're a disgrace. And the next time I see Michael I'm not going to be so nice," he said.

A representative for Bloomberg News said it stands by its reporting for the article.

Although Trump called Bloomberg a friend, he continued to bash him in the interview with the Daily Mail, going as far to say he won't be using a Bloomberg terminal for his business.

"If they're as inaccurate with their other financial reporting as they are on my kind of stuff, and the way they cover me politically I wouldn't have one of their little screens. I wouldn't waste my money on it," he said.

Trump, 69, also went on the defensive yesterday over a past controversial remark against a female attorney who requested a break to pump breast milk for her then-infant daughter.

Trump did not deny getting angry and calling the woman "disgusting" in 2011 but lashed back after reports of the incident emerged late on Tuesday.

Miami-based lawyer Elizabeth Beck was questioning the wealthy developer and television personality in a Florida real estate case when she asked for the break, according to court testimony first reported by The New York Times.

Trump abruptly ended the deposition and questioned his own lawyer's request for a bathroom break, according to the testimony.

"She wanted to breast pump in front of me at dep(osition)," Trump tweeted Wednesday. Beck told Reuters that was untrue.

"I'm exasperated now because he's telling falsehoods," she said.

Trump, known for his brash style, has come under fire for his comments on Mexican immigrants, veterans and other Republican presidential candidates even as he climbs in opinion polls.

The latest flare-up came after a top adviser to Trump apologized on Tuesday for making "inarticulate" comments on the subject of marital rape that also generated controversy.

Beck recounted on CNN Wednesday, "He got up, his face got red, he shook his finger at me and he screamed, 'You're disgusting, you're disgusting,' and he ran out of there."

Afterward, Trump fired back on Twitter: "So many people who know nothing about me are commenting all over T.V. and the media as though they have great D.J.T. insight. Know NOTHING!"

But Beck defended her remarks and said she had witnessed his behavior during numerous in-person interactions with the mogul over several years.

"I know what I saw," she said. "You know how they behave in certain circumstances."

Trump lawyer Alan Garten told the Times he thought Beck's request was a bid to buy time, but his comments did not reflect a position on breast-feeding.

Beck, whose firm is still involved in litigation with Trump, rejected that argument and said Trump later flew to her law office in Miami to finish the deposition.

The Times also cited depositions for several lawsuits since 2007 that it said showed the candidate's raw edge and his tendency to exaggerate business deals.
