HEMPSTEAD, N.Y. — Police on Long Island say about 2,000 protesters have gathered outside the scene of the first presidential debate between Hillary Clinton and Donald Trump.

Some of the diverse groups protesting Monday night’s showdown at Hofstra University include Hardhats for Hillary, socialists and activists calling for a living wage and financial revolution.

The protesters have been confined to an area several blocks long.

Nassau County police say 24 people have been arrested on mostly disorderly conduct charges. Police gave no other details on the arrests.

Interest in the presidential race has been intense, and the campaigns are expecting a record-breaking audience to watch the 90-minute televised debate.
