Republican and Democratic voters in Iowa's 99 counties will convene on Monday night for the state's presidential caucus -- the first official competition in both parties' primary process.

As the Daily Beast reported, the process is scheduled to begin at 8 pm EST and conclude three or four hours later.

According to Agence France-Presse, former Secretary of State Hillary Clinton is leading among Democratic candidates, while real estate magnate Donald Trump continues to hold a lead in the GOP race.
