Rudolph Giuliani has spent days on newspaper front pages and dominating cable news this week, with some suggesting he has placed his own client, the president of the United States, in fresh legal jeopardy.

Among those closely watching Giuliani's performance, it's certain, are his fellow shareholders at Greenberg Traurig. In a move that legal ethics experts suggest is uncommon, Giuliani has remained with the firm but taken a leave of absence to represent President Donald Trump.

After joining Trump's legal team last month, the former New York City mayor initially remained on Greenberg Traurig's website as senior adviser to Greenberg's executive chairman and as the firm's cybersecurity practice chair. His firm profile was taken offline this week, amid the furor sparked by his comments on Fox News about payments to the woman known as Stormy Daniels, and after ALM sent Greenberg questions on Wednesday about the affiliation.
