Pro-Israel groups are mobilizing against Sen. Rand Paul for his block on legislation to give Israel $38 billion over the next 10 years. AIPAC is placing Facebook ads & CUFI is sending emails to pressure Paul, “the last obstacle” to Israel obtaining the largest military aid package in US history…

Free Beacon reports that “pro-Israel groups in America are mobilizing against Sen. Rand Paul (R., Ky.) for blocking the continuation of U.S. aid to Israel.”
Paul has placed a “block” on legislation to give Israel $38 billion over the next 10 years – $23,000 per every Jewish Israeli family of four. This is the largest military aid package in U.S. history and amounts to $7,230 per minute to Israel, or $120 per second. A stack of $38 billion dollar bills would reach ten times beyond the international space station.
A block is a legislative procedure in which a senator calls on the floor leader not to move forward with a bill and indicates that the senator may filibuster against it.
Jewish News Syndicate reported last week that the American Israel Public Affairs Committee (AIPAC) had sent an action alert to its members calling on them to pressure Paul to remove his block on the bill, ‘‘S. 2497 Ileana Ros-Lehtinen United States-Israel Security Assistance Authorization Act of 2018.’.................https://israelpalestinenews.org/pro-israel-groups-attack-rand-paul-for-blocking-38-billion-to-israel/
