California Senator Kamala Harris announced on Tuesday that she is ending her bid for the 2020 Democratic presidential nomination, an abrupt close to a candidacy that held historic potential.

“I’ve taken stock and looked at this from every angle, and over the last few days have come to one of the hardest decisions of my life”, Harris told supporters via email.

“My campaign for president simply doesn’t have the financial resources we need to continue”, Harris added.

A senior campaign aide said Harris made the decision Monday after discussing the path forward with family and other top officials over the Thanksgiving holiday.

She raised an impressive $12 million in the first three months of her campaign and quickly locked down major endorsements meant to show her dominance in her home state, which offers the biggest delegate haul in the Democratic primary contest.

Former Vice President Joe Biden, who had a memorable debate stage tussle with Harris this summer, called the senator a “solid person, loaded with talent.”

Earlier in September, the senator had apologised after facing criticism that the Democrat presidential candidate laughed at an offensive remark about President Donald Trump.

Harris took to Twitter, saying “When my staff played the video from my town hall yesterday (Friday), it was upsetting. I didn’t hear the words the man used in that moment, but if I had I would’ve stopped and corrected him. I’m sorry. That word and others like it aren’t acceptable. Ever”.

Harris has been one the fiercest critics of Donald Trump among the 2020 candidates, directly attacking the embattled president and repeatedly calling for his impeachment.

Harris was the third candidate to drop out in recent days, along with low-polling Democrats Montana Governor Steve Bullock and former congressman Joe Sestak.
