It looks like Marc Kasowitz will go down in history as President Donald Trump’s lawyer. But while America is just getting to know him, the same can’t be said for his fellow elite litigators, especially in New York.

Now reportedly poised to lead the president’s outside legal team amid expanding Russia investigations, Kasowitz has long had a reputation as a hard-nosed trial lawyer, with a hands-on approach to running and growing the firm he co-founded in 1993, now known as Kasowitz Benson Torres. (A spokeswoman for Kasowitz’s firm didn’t respond to a request to confirm his assignment or comment on his role.)
