Here’s the latest I can provide based on widely reported events up to 2020:
Tulsi Gabbard ended her 2020 presidential campaign on March 19, 2020, suspending her bid and endorsing Joe Biden for president. This blocked further participation in primaries and debates as the race focused on Biden and Bernie Sanders. She stated she would support Biden to help unite the country.[2][3][8]
Prior to suspending, Gabbard had been a long-shot candidate with limited polling and debate presence, despite some regional fundraising and a small delegate showing (e.g., Samoa caucus delegates). The campaign had publicly clashed with other figures (notably Hillary Clinton) and she chose to exit while backing Biden.[3][4][7]
After exiting, coverage highlighted that she sought to influence the Democratic nomination by endorsing Biden and encouraging that the party unify behind him against the eventual nominee, Bernie Sanders, who remained in the race for a time.[5][3]
If you’d like, I can pull more recent context about Tulsi Gabbard’s public activities after 2020 (e.g., shifts in endorsements or involvement in public discourse) and provide up-to-date sources.
