Sen. Tom Cotton is urging the Biden-Harris administration to provide biweekly briefings on the investigation into a leak of classified US intelligence on Israel's preparations for an attack on Iran. Cotton expressed concern over the breach of trust and the potential impact on the US-Israel relationship. The leaked documents, which detail Israeli military preparations, likely originated from an American source and have raised concerns about the security breach. Congress is pushing for a thorough investigation and swift action to identify the perpetrator.
