Unable to generate broad interest in her bid for the White House, Rep. Tulsi Gabbard (D-HI) announced on Thursday that she was dropping her bid for the White House, and endorsing former Vice President Joe Biden.

"After Tuesday's election it's clear that Democratic primary voters have chosen Vice President Joe Biden to be the person who will take on President Trump in the general election," Gabbard said in a video message from her home state.

"I’m suspending my presidential campaign and offering my full support to Vice President Joe Biden," Gabbard said.

"I'm confident that he will lead our country, guided by the spirit of aloha," she added.

While Gabbard was still officially in the race, and on the ballot, the Hawaii Democrat had been doing few campaign events in recent weeks.

Gabbard's decision leaves only Sen. Bernie Sanders - who is not a member of the Democratic Party - as a major candidate against Biden.

Sanders was said to be assessing his campaign, after Biden easily won Arizona, Florida, and Illinois on Tuesday, extending his delegate lead in the Democratic race.
