Secretary of State Antony Blinken is set to make a last-minute case Tuesday for a plan for the post-war reconstruction and governance of Gaza as a ceasefire between Israel and Hamas appears tantalizingly close to completion.

Blinken will tout the proposal, which has been in the works for a year, and discuss the importance of ensuring its success after the Biden administration leaves office in a speech to the Atlantic Council, a Washington-based think tank, according to a U.S. official, who spoke on condition of anonymity to preview the speech.
