President Joe Biden and President-elect Donald Trump are both claiming credit for Israel and Hamas agreeing to a ceasefire deal in Gaza after the White House brought Trump’s Middle East envoy into negotiations that have dragged on for months.

Months of tedious talks over a ceasefire and hostage deal in Gaza – negotiations that required officials from an outgoing and incoming presidential administration to put aside their fundamental differences – culminated in an intense late-night push for an agreement that finally came to fruition on Wednesday.

Biden confirmed the ceasefire agreement in a speech on Wednesday afternoon, noting that it was his administration who negotiated the deal but it will be Trump’s administration that ensures it is implemented. The agreement comes after a 15-month-war wreaked havoc across Israel and Gaza, resulting in thousands of deaths.

White House principal deputy national security adviser Jon Finer said on Sunday that President-elect Trump’s team provided “significant support” in the recent ceasefire deal between Israel and Hamas.
