CEO & President

Josh Block is a communications, foreign policy and political strategist involved in national politics and policy for nearly 20 years. A former Clinton Administration official & spokesman at the State Department’s USAID, Block got his start on Capitol Hill in the office of Senator Edward M. Kennedy and Democratic politics. A spokesman for the Clinton/Gore and Gore/Lieberman presidential campaigns, Block also worked on House and Senate races, including Sen. Chuck Schumer’s (D-NY) first campaign for U.S. Senate, the ’96 Presidential Inaugural Committee, and as spokesman at the Ohio Democratic Party.

After nearly a decade on the senior staff of AIPAC, one of Washington’s most respected and effective advocacy organizations, where he was Spokesman and Director of Strategic Communications, Block was appointed Senior Fellow at the Progressive Policy Institute in Washington D.C., and established a strategic consulting practice focused on the intersection of policy, politics and public affairs for international and US-based clients in the public and private sector.

Block was named by Foreign Policy Magazine to its Twitterati 100 list of the most influential foreign policy experts on Twitter (@JoshBlockDC) and The Forward to its list of America’s 50 most influential Jews. When he was appointed CEO and President of The Israel Project, AIPAC President Michael Kassen said, “TIP, as well as the pro-Israel community, will benefit greatly from [Block’s] unique ability to shape the debate and educate both policymakers and the public about Israel and the Middle East.”
