Former New York City mayor Rudy Giuliani asserted his innocence and slammed the Justice Department’s investigation into his alleged dealing with Ukraine during a recent interview.

According to The Hill:

“I committed no crime, and if you think I committed a crime, you’re probably really stupid, because you don’t know who I am,” Giuliani said in an interview with NBC New York.

Federal prosecutors raided Giuliani’s New York apartment and law office in April.

They are specifically examining if Giuliani illegally lobbied the Trump administration for Ukrainian oligarchs, who are the same officials that were helping look for dirt on former Trump’s political rivals, including then-Democratic presidential candidate Joe Biden.

Giuliani, however, says he is innocent, saying that he was working for Trump as a lawyer at the time of the alleged contact.

“Is the guy who put the mafia in jail, terrorists in jail, Ed Koch’s commissioners in jail, and the worst people on Wall Street — I’m not going to file [a form]? I mean, that’s just crazy,” Giuliani, a former mayor of New York City and U.S. attorney for the Southern District of New York, told NBC New York.

Giuliani also noted the drastic differences between investigations and allegations made against Republicans compared to those made against Democrat lawmakers. The former Trump attorney specifically noted drastic biases between allegations made against him compared to New York Governor Andrew Cuomo’s nursing home scandal and Hunter Biden’s laptop.
