Jonathan’s nearly 40 years of professional media and reporting experience has been enhanced by a Yale Law School Masters Degree fellowship program, from which he graduated with honors in First Amendment Law from internationally renowned attorney Floyd Abrams and then Yale University President Benno Schmidt.

Jonathan is the author of the critically acclaimed biography Staking A Claim: Jake Simmons and the Making of an African-American Oil Dynasty, which a Washington Post Book World front page review called, “a rare biography that challenges the readers senses in the same the way science fiction does.”  In 1992, he edited Buying America Back: Economic Choices for the 1990′s, an anthology of 45 progressive solution-oriented essays called by Publisher’s Weekly,  “An immensely important resource for policymakers, community activists, and everyone concerned with building a more humane future.”

Jonathan directed media and public policy campaigns and was the City Council’s lead analyst for federal relief programs. Jonathan’s work resulted in more than $250 million of federal funds being re-directed to needy businesses and constituents near the World Trace Center, as well as winning a reversal of a federal plan to move the U.S. Customs House from its historic home of more than 200 years in Lower Manhattan to New Jersey.
