Rosen has been brought in by Trump’s longtime personal attorney, Michael Cohen, to handle the legal issues surrounding the so-called “hush” agreement that Cohen negotiated with the adult film actress known as Stormy Daniels, according to three people familiar with the arrangement.

Rosen, a partner in the firm LaRocca, Hornick, Rosen, Greenberg & Blaha, is a “pit bull” who will “aggressively fight and use his rhetorical and writing skills to get you a win,” according to the firm’s website. The firm is based out of The Trump Building on Wall Street in Manhattan’s financial district.

According to the law firm’s website, Rosen represents companies and “high net worth individuals in a myriad of areas of business and commerce,” and also serves as an economic development official for his New Jersey hometown.
