President Trump blasted the “Failing” New York Times for writing a “hit piece” on him after the newspaper published a story saying he amassed his billion-dollar fortune by helping his parents “dodge taxes” and through “outright fraud.”

“The Failing New York Times did something I have never seen done before. They used the concept of ‘time value of money’ in doing a very old, boring and often told hit piece on me,” the president wrote on Twitter Wednesday. “Added up, this means that 97% of their stories on me are bad. Never recovered from bad election call!”

The newspaper, in a more than 14,000-word report, said Trump received more than $413 million in today’s dollars from the real estate empire his father began.

The president has previously said he parlayed a $1 million loan from his dad, Fred Trump, into his billion-dollar real estate business.

The report said the Trump family used “sham” corporations to disguise gifts from the father to his children over the years and routinely undervalued his properties to avoid hefty tax payments.
