The US president Donald Trump has imposed a full travel ban on 12 countries mainly in Africa and the Middle East, following through on a promise made in 2024 on the campaign trail. But why has the president chosen to implement the ban now, and how likely is it to survive a legal challenge?

The ban includes Afghanistan, Iran, Somalia and Libya. But there’s also confusion as to why Egypt remains off the list despite the president citing the recent attack Colorado's Jewish community, which was allegedly carried out by an Egyptian national. There are also partial restrictions on seven other nations including Venezuela and Cuba.

And, in another instalment of Donald Trump’s war with Harvard, he’s also suspended foreign students from studying at the university, which could have a big impact on Chinese students. Sarah’s been chatting to Nicholas Burns, a former US ambassador to China who now teaches at Harvard, about how the university should respond to the president, and what it’s like to negotiate in a room with Xi Jinping.
