WASHINGTON (AP) – Beto O’Rourke is the latest former Democratic presidential candidate to endorse Joe Biden. The former Texas congressman appeared at Biden’s rally in Dallas on Monday night, along with Amy Klobuchar, who ended her own 2020 bid earlier in the day. To cheers, O’Rourke said, “Tomorrow, March 3, 2020, I will be casting my ballot for Joe Biden.” Biden also nabbed the endorsement of Pete Buttigieg, who suspended his campaign on Sunday night and appeared with the former vice president ahead of Monday night’s rally. O’Rourke ended his own White House run last year after failing to recapture the enthusiasm, interest and fundraising prowess of his 2018 Senate bid.
