California Senator Kamala Harris’ endorsement of former vice president Joe Biden as Democratic Party nominee for the 2020 election has been mocked as looking like a hostage video.

On Monday’s edition of The Daily Show, host Trevor Noah said that video, filmed on a cellphone in front of a brick wall, “looked weird” before likening it to a ransom note.

After playing the video, he joked: “Now, please send $10,000 in unmarked bills so that my family can see me again.”

He added: “I bet even the Taliban is looking at this video, like: ‘We had better lighting and we were in a cave!”

Ms Harris’ endorsement came just ahead of Tuesday’s primaries in which six states — Idaho, Michigan, Mississippi, Missouri, North Dakota and Washington — will choose between Mr Biden and Bernie Sanders.

The Washington Post reports that Ms Harris had a particular reason for waiting until now to endorse Mr Biden: “I had two women colleagues in the race, and I did not feel right putting my thumb on the scale [that] in any way would harm their candidacy.”

She added: “So, when Elizabeth announced that she was getting out of the race, I let Joe know that I would endorse him.”

While Mr Biden and Ms Harris sparred during the primary debates, particularly over the issue of school busing, the California Senator is seen by pundits as a possible running mate for the former vice president.
