A leading member of the congressional Israel caucus says the Obama administration is fueling hatred against the Jewish state following comments by a top U.S. diplomat accusing Israel of not upholding democratic rule of law, according to a letter sent Wednesday to the State Department and obtained by the Washington Free Beacon.
Rep. Peter Roskam (R., Ill.), co-chair of the House Republican Israel Caucus, lashed out at the administration, chastising it for seeking to inflame a diplomatic fight with Israel as the Jewish state grapples with a new wave of Palestinian terror attacks that has killed and wounded many civilians.
Dan Shapiro, the U.S. Ambassador to Israel, elicited a sharp rebuke from Israeli leaders Tuesday when he accused the Jewish state of failing to properly investigate crimes committed against Palestinians.
