One day before Egyptian President Abdel Fattah el-Sisi’s visit to the White House, senators from both parties sent a letter to Secretary of State Mike Pompeo on Monday urging him to address “the erosion of political and human rights” in Egypt during his discussions with the autocratic leader.

Lawmakers raised concerns about Sisi’s government ahead of Tuesday’s negotiations between the United States and Egypt to discuss their strategic partnership and priorities in the Middle East. The letter was signed by 17 senators, including the Foreign Relations Committee chairman, Jim Risch (R-Idaho), and ranking member, Bob Menendez (D-N.J.).
