Matthew Miller, a senior official in former US president Joe Biden’s administration has told Sky News that he has no doubt that Israel has committed war crimes in Gaza.

Speaking to the Trump 100 podcast, Matthew Miller, who, as a state department spokesman, was the voice and face of the US government’s foreign policy under Mr Biden, revealed disagreements, tensions and challenges within the former administration.

“Look, one of the things about being a spokesperson is you’re not a spokesperson for yourself. You are a spokesperson for the president, the administration, and you espouse the positions of the administration. And when you’re not in the administration, you can just give your own opinions.”

Now out of office, he offered a candid reflection of a hugely challenging period in foreign policy and US politics.

Asked about Gaza, he revealed there were “small and big” disagreements within the Biden administration over the US-Israel relationship.

“There were disagreements all along the way about how to handle policy. Some of those were big disagreements, some of those were little disagreements,” he said.

Pushed on rumours that then-secretary of state Antony Blinken had frustrations with Mr Biden over both Gaza and Ukraine policy, Mr Miller hinted at the tensions.
