Two key Democrats in the US Congress have agreed to support a major arms sale to Israel that includes 50 F-15 fighter jets worth more than $18 billion, the Washington Post reported, citing three unnamed officials, according to Reuters.

Representative Gregory Meeks and Senator Ben Cardin have signed off on the deal under heavy pressure from the Biden administration after the two lawmakers had for months held up the sale, the Post reported.

“Any issues or concerns Chair Cardin had were addressed through our ongoing consultations with the (Biden)Administration, and that’s why he felt it appropriate to allow this case to move forward,” Eric Harris, communications director for the Senate Foreign Relations Committee, told the Post in a statement.

Meeks told the paper that he had been in close contact with the White House and had urged them to pressure Israel over humanitarian efforts and civilian casualties. He said the F-15s would not be delivered until “years from now,” according to the Post.
