Congressman Ted W. Lieu (D-Los Angeles) is leading a bipartisan group of 64 Congress members in sending a letter to President Barack Obama urging him to postpone the sale of new arms to Saudi Arabia.

The goal is to give Congress sufficient time to debate the merits of the deal in light of the Saudi-led Coalition’s operational conduct in Yemen. The letter is co-led by Reps. Ted Yoho (R-Fla.), John Conyers (D-Mich.), and Mick Mulvaney (R-S.C.). Lieu previously raised concerns last September about the coalition’s killing of civilians in letters to the chairman of the Joint Chiefs of Staff and to U.S. Secretaries John Kerry and Ash Carter in March.

Additionally, Lieu introduced legislation to establish new guidelines for weapons sales to Saudi Arabia.

“The actions of the Saudi-led Coalition in Yemen are as reprehensible as they are illegal. The multiple, repeated airstrikes on civilians look like war crimes,” Lieu said. “Hospitals, schools and wedding parties are not legitimate military targets. Saudi Arabia is either intentionally targeting civilians or deliberately indifferent in executing its military operations. Either case flies in the face of long-standing international standards of conduct. The United States of America should never support such atrocities in any way. They are not only immoral and unlawful, but they seriously harm our national security and moral standing around the world.”

The letter is supported by Amnesty International USA, International Christian Concern, Friends Committee on National Legislation, Just Foreign Policy, Americans for Democracy & Human Rights in Bahrain and other organizations. To read the full text of the letter, visit www.lieu.house.gov.
