Celebrities speak out, join thousands protesting against Donald Trump's 'Muslim ban'

As thousands of Americans flooded airports in the wake of President Donald Trump's 'Muslim ban' – which prohibits entry to the US for citizens of seven predominantly-Muslim countries – celebrities have joined in the protests both on the ground and online.

Filmmaker Michael Moore was in the thick of the demonstration at JFK airport, using his considerable social media presence to broadcast the scene and also encourage others to follow him.

And follow they did.
