Kamala Harris received a better score from swing voters during her Fox News interview on Wednesday than her general popularity with this group, according to a study. Online monitoring and analysis company Impact Social reported that 20 percent of swing voters who watched the interview had a positive impression of Harris.

Vice President Kamala Harris has not submitted to many interviews with journalists during her short presidential campaign, and certainly none with conservative media.

Harris addressed the media on the killing of Hamas' military leader. At rallies later in the day, she criticized Trump and focused on economic plans.

Harris campaign is pushing to shore up support in the “blue wall” states of Wisconsin, Michigan and Pennsylvania less than a month before the Nov. 5 election.
