As counsel to President Donald Trump, former New York City Mayor Rudolph Giuliani has made statements, ostensibly in his client's defense, that have left some in the legal realm scratching their heads.

One critic, a retired federal appellate judge, even asked in a letter to the editor of the New York Law Journal why the former mayor and Manhattan U.S. attorney hasn't been brought up on disciplinary charges.

As for New York attorneys who have worked closely with Giuliani and the offices he has led in the past, some recall his days as the hard-charging U.S. attorney for the Southern District of New York or the two-term mayor who took credit for making New York City safe and leading the city in the wake of the Sept. 11, 2001, terrorist attacks and wonder what's become of him.
