Joe Biden: key takeaways from his Nato press conference

The president was more at ease on foreign policy - but his remarks were overshadowed by a couple of high-profile gaffes

During Joe Biden's press conference at the Nato summit, which many described as a test for the future of his re-election bid, he demonstrated clarity and conviction on foreign policy. But much was overshadowed by a couple of awkward gaffes and a shaky voice, at a time when the US is hyper-focused on his fitness to lead.

After roughly eight minutes of prepared remarks, Biden answered reporters' questions on Nato, Ukraine, China and Israel, and just as many on his cognitive health and his vow to stay in the race.
