Incumbent Republican Dana Rohrabacher and Democratic challenger Harley Rouda meet in their first and possibly only debate for one of the nation's most hotly contested Congressional seats. The coastal Orange County district is one of the "toss-up" races that could determine control of Congress and the fate of the Trump presidency. The candidates discuss President Trump, the Brett Kavanaugh hearings, the state of the economy, immigration and U.S. relations with Russia.
