Democratic candidate, Kamala Harris, held a star-studded rally hosted by talk show legend Oprah Winfrey on Thursday in a bid to dazzle voters, as rival Donald Trump criticised Jewish Americans for not voting for him.

Hollywood stars including Jennifer Lopez, Meryl Streep, Julia Roberts, Chris Rock and Ben Stiller beamed remotely to lavish praise via screens on the United States Vice President.

Sitting on a chat-show-style stage, Winfrey started by asking Harris about what seemed a sudden burst in confidence — “a veil or something dropped” — after she replaced President Joe Biden as the nominee.

“We each have those moments in our lives when you have to step up,” the 59-year-old Harris replied at the live-streamed “Unite for America” event.

The pair hugged as Harris arrived on stage at the rally in Michigan, one of the seven crucial battleground states that will decide the knife-edge November 5 election.

Harris urged Americans to unite against the “powerful forces that would try to divide us”, represented by Republican former president Trump.
