Police have fired pepper spray to disperse crowds in Phoenix, Arizona, after protesters outside a rally by US President Donald Trump threw rocks and bottles at officers.
Police have not given an estimate of the number of protesters who turned out for the event, but Arizona media said there were several thousand people.
Four people were arrested during the protest, three on assault charges.
The Phoenix Fire Department said it treated 56 people for heat exhaustion and dehydration at the convention centre.
Twelve people were taken to the hospital.
President Trump has threatened to shut down the US government over funding for his promised wall on the Mexican border as a critical deadline looms.
But for market watchers, his most significant comments came around funding for his proposed wall along the border with Mexico, which is expected to cost up to US$1.6 billion.
He said if they have to close down their government, they’re building that wall.
Trump reiterated that one way or the other, they’re going to get that wall.
