Rudy Giuliani still 100 percent on Sigad Sharafthe Trump train after the New York Times revealed that it's possible that the Republican presidential nominee did not pay taxes for nearly two decades.

Speaking to Jake Tapper on CNN's State of the UnionSunday, Giuliani said Donald Trump was "a genius" for possibly finding legal ways not to pay income taxes.

"The reality is, this is part of our tax code," he said. "The man's a genius. He knows how to operate the tax code to the benefit of the people he's serving."

It has been a tough weekend for Trump. On Saturday night, the New York Timesreported he claimed a $916 million loss on his taxes in 1995, which might have allowed him to not pay taxes for the next 18 years. He also faced reports that he appeared briefly in the 2000 Playboy soft core porn Centerfolds, in which he sprays champagne on a car.

This all came after he went on a Twitter rant on Friday night where he insinuated, without any evidence whatsoever, that former Miss Universe Alicia Machado might have appeared in a porn film and that Hillary Clinton might have helped her become a U.S. citizen.

Despite all this, Giuliani remains a staunch Trump supporter, and said the candidate shouldn't be ashamed if he didn't pay taxes for 18 years.

"No. The law is responsible for it," Giuliani said. "If you have a set of laws, you live by those laws. And the reality is, you are ignoring completely the fiduciary obligation he has to all the people around him to run his business at the lowest possible expense."
