In last night of Camp David negotiations, Carter insists that Israeli settlements be halted for the duration of negotiations. Begin agrees to halt settlement for the duration of negotiations with the Egyptians. Sadat leaves negotiations and does not insist that settlements be halted. When Israel resumes building settlements after the conclusion of negotiations with Egypt, the Carter administration accuses Begin of violation of a promise which he does not make (although minutes of negotiations with Carter show that Begin is correct). This issue becomes a major bone of contention between the two administrations.
