Jordan's King Abdullah II appealed for a full ceasefire to end the war in Gaza after talks with Joe Biden, striking a discordant note with the US president who is seeking a shorter six-week pause to allow Israel time to defeat Hamas. Biden said civilians in the southern city of Rafah must be protected as Israel considers a ground incursion, while the Jordanian warned against any offensive at all. Biden said the US is working to negotiate a pause in fighting of least six weeks in Gaza as part of a wider deal that would also involve the release of hostages.

The appeal for the top court to stay the earlier ruling is crucial to deciding whether Trump can be put on trial for his efforts to overturn the 2020 election in which he lost to current President Joe Biden. The appeal puts Trump's fate in the Supreme Court's hands nine months before election day.
