Kamala HarrisKamala HarrisTwo 'View' hosts test positive for coronavirus ahead of Harris interview Rep. Karen Bass to run for mayor of Los Angeles: report Biden taps big bank skeptic to for top regulatory post MORE (D-Calif.), is being treated “unfairly” by the mainstream media.
“I don’t think she has been treated fairly,” Dyson, who is also the founder and CEO of nonprofit organization Women’s Global Initiative, told Hill.TV's Krystal Ball and Buck Sexton during an interview on "Rising."
"That’s something that I know that the pundits and the people around her are trying to do better themselves and how you can use certain platforms outside of the regular media," she continued.
Dyson's remarks were in response to a question from Ball on whether Harris had received enough attention from the press.
Dyson, who was also a former chief of staff to two-time presidential candidate Rev. Jesse Jackson, also offered her own advice for the Harris campaign.
“I think she has great gravitas in certain circles but I think they need to find ways to expose her a little bit more,” she added.
Dyson recommended that the California senator break away her immediate base and seek broader support among voters.
“Part of the problem is that she has sequestered herself by her idea of who her base would be when all of America is her base,” she said.
A spokesman for Harris didn't immediately respond to a request for comment.
Harris, who officially launched her presidential campaign in January, has been struggling in recent polls.
A Morning Consult survey released Monday found that just seven percent of Democratic primary voters would support Harris, while eight percent said they'd favor Sen.
