On the Presidential campaign trail, Rudy Giuliani's extraordinary accomplishments as New York City's Mayor - fighting crime, cutting taxes, reducing welfare rolls, and bringing jobs back to our city - have become well known. But before he was our mayor, he was a crusading prosecutor whose leadership, drive, creativity, independence, and integrity tell us much about what kind of President he will be - a great one.

I worked side-by-side with Rudy when he was the U.S. Attorney in Manhattan in the mid-1980s and saw first-hand how he tirelessly took on the Mob, white collar crime, drug dealers, and corrupt public officials, with unprecedented success and a more than 90 percent conviction rate. And I saw first-hand how he stood his ground, even when it wasn't the popular or politically expedient course, because of his unwavering commitment to do the right thing.

Here are some examples.

Organized Crime

Putting his personal safety at risk and facing death threats for it, Rudy took on the Mob - and won. He used the RICO statute in innovative ways to wipe out the top echelon of the major La Cosa Nostra Families, and then, in his greatest triumph, put away the heads of the five New York Families - known as "the Commission" - for 100 years each. He also successfully tackled the Sicilian Mafia in the famous "Pizza Connection" drug case. And he broke La Cosa Nostra's long-time stranglehold over the Teamster Union's leadership by securing independent union oversight and direct rank-and-file democratic elections of top Teamster officials.

White Collar Crime

Rudy also had the courage to take on Wall Street when its excesses crossed the line from greed to criminality in the 1980s. He convicted such notorious white collar criminals as Ivan Boesky, Dennis Levine, Marc Rich, and Michael Milken, who later bonded with Rudy as a fellow cancer survivor.
