LAS VEGAS — Presidential hopeful Hillary Clinton is campaigning in Las Vegas alongside the Democratic candidate who’s locked in a competitive and pivotal U.S. Senate race.

Clinton is scheduled to headline a rally at 7:30 p.m. Wednesday at the Smith Center for the Performing Arts. She’ll appear with Senate candidate and former Nevada Attorney General Catherine Cortez Masto.

The rally comes as Cortez Masto trails slightly in recent polls in the race to replace retiring Sen. Harry Reid. The contest could decide which party holds the majority in the U.S. Senate.

Clinton’s campaign raised the curtain on her visit by releasing new ads in Spanish featuring prominent Nevada DREAMer Astrid Silva, who talks about the risks to her if Donald Trump is elected and makes good on his immigration campaign promises.
