Changes are planned for an event this week in Las Vegas for former Maricopa County, Arizona Sheriff Joe Arpaio.  That's after Las Vegas police raised concerns about the event.  

President Trump pardoned Arpaio last month after the former lawman was convicted of defying a court order instructing his department to stop detaining suspected illegal immigrants.  

Arpaio was set to receive the Conservative Leadership Conference's Courage Under Fire Award on Saturday night at the Tropicana Hotel.  

Police worried the event could spark violent protests.  The event has since been moved to an undisclosed location.  Whether Arpaio plans to attend is not clear.
