It’s not unusual for rallies to be packed, with people walking in and out of the venue in a matter of minutes.
But there’s a catch.
Trump, a reality TV star and presidential candidate, has made some controversial remarks during his rallies, including a threat to ban Muslim immigration.
He’s also called Mexicans “rapists” and promised to deport millions of undocumented immigrants.
While Trump’s rallies have been more or less peaceful, the Nevada Desert is an unpredictable place.
It’s also not uncommon for protesters to clash with police.
A crowd of about 50 people is expected in the parking lot of the Reno-Sparks Convention Center in Reno on Thursday.
But it’s unclear if the Trump rally will go on as planned.
The Reno Gazette-Journal reported that protesters have planned to block the entrance to the venue and are trying to get the police to clear the street for the event.
But Nevada law prohibits the use of a “riot device,” and police have not said if they will use force to clear protesters from the street.
A Nevada law passed in 2006 prohibits protesters from blocking or attempting to block public entrances to any public building.
The Nevada Legislature approved a law that bars protesters from using violence or other acts to prevent or hinder public access to a public building, including to a building owned or controlled by the state.
In the past, Trump has accused protesters of trying to disrupt his rallies.
In February, Trump said he was “not going to allow protesters to destroy the rally.”
