President Joe Biden addressed the nation Thursday night following a trip to Tel Aviv as the Israel-Hamas conflict drags into its second week.

Biden said he'll be sending Congress an "urgent budget request to fund America's national security needs to support our critical partners, including Israel and Ukraine."
