The most famous First Amendment attorney in the country, Abrams is the lawyer who many prominent New Yorkers call when they get in trouble for something they've said or written. He's the father of MSNBC's Dan Abrams.

A New York native and Yale Law grad, Abrams joined Cahill Gordon & Reindel in 1963, making partner seven years later. His career-making case came in 1972, when he successfully defended the New York Times over its publication of the Pentagon Papers. The landmark decision remains one of the most significant events in the history of modern media, and changed the way reporters cover politics. Abrams has since represented a slew of major media organizations against charges of libel or disclosing confidential information. He defended CNN after it accused the U.S. government of using nerve gas in Laos; he defended NPR after the network "leaked" information during confirmation hearings for Clarence Thomas; and he came to NBC's aid after Wayne Newton sued the network for libel in 1986 after news reports linked him to the Mafia. More recently, he represented the New York Times's Judy Miller and Time's Matt Cooper in their efforts to avoid revealing their confidential sources. In addition to his legal practice, Abrams also teaches a class on First Amendment issues at the Columbia Graduate School of Journalism.

In 2005, Abrams published a memoir, Speaking Freely: Trials of the First Amendment, which recounted some of his most notable cases over the years.
