Hundreds of police are flooding a Florida campus

Hundreds of police are flooding a Florida campus as a white nationalist is due to speak later at an event that has provoked a state of emergency.

The University of Florida says it was obligated under law to allow the event and no one invited Richard Spencer.
About 3,000 people have signed up on a Facebook page to attend a protest rally called "No Nazis at UF".
It comes two months after a far-right rally in Charlottesville, Virginia, led to deadly clashes.
Mr Spencer's organisation, the National Policy Institute, is vetting reporters it will allow inside to cover the speech.
Critics have lamented that the college, which reluctantly permitted the event in order to protect Mr Spencer's free speech rights, will let him choose which journalists are allowed to cover it.
