Palestinian-American lawmaker Rashida Tlaib on Friday turned down Israel's offer to let her visit her grandmother in the occupied West Bank, owing to restrictions she termed oppressive. It was the latest twist in a saga hinging on Israel's war against those who would boycott it over its treatment of the Palestinians. On Thursday, Israel barred from entry the US Congress' first Muslim female lawmakers, Tlaib and Ilhan Omar, on the grounds that they support the boycott movement, and after President Donald Trump urged the Jewish state to block the two Democrats.
