(CNN)Michael Cohen served loyally as Donald Trump's right-hand man for more than a decade, taking care of anything and everything the New York real estate baron needed to get done. On November 8, 2016, Cohen's stock suddenly soared: He was now the personal attorney to the President-elect of the United States, with unique understanding of a man that everyone was scrambling to get access to. Cohen quickly got to work. According to multiple people familiar with Cohen's conduct following the election, he aggressively pitched himself to potential clients, reminding them of his proximity to the most powerful man in the world. Those efforts landed Cohen lucrative consulting deals. New reporting this week revealed that in the months following the 2016 election, Cohen received hundreds of thousands of dollars from powerful entities based in and outside of the United States. "I don't know who's been representing you, but you should fire them all. I'm the guy you should hire. I'm closest to the President. I'm his personal lawyer," was how one GOP strategist described Cohen's sales pitch. One company that Cohen immediately sought out was pharmaceutical giant Novartis. "He was shopping himself around," a source familiar told CNN. Cohen would ultimately land a one-year contract with the firm by promising access to the White House on health care policy.
