2020 Democratic presidential candidate and tech entrepreneur Andrew Yang scored a major endorsement this weekend from fellow tech entrepreneur Elon Musk, the founder of PayPal who now leads SpaceX and Tesla.

“I support Yang,” Musk tweeted in response to another tweet commenting on a post from Yang urging voters to have an open mind.

Musk’s tweet was a welcome endorsement for Yang, who has struggled to garner support in the crowded field of candidates in the Democratic primary.

While he has qualified for the third set of Democratic debates to be held in Houston in September, which featured higher thresholds to participate than previous debates, Yang remains a long-shot candidate who has made providing a universal basic income the centerpiece proposal of his campaign.

Musk agrees with Yang’s signature policy. It features handing out a “Freedom Dividend” of $1,000 a month to every American over the age of 18. Musk told one Twitter user the policy was “obviously needed.”

Musk endorsed the Democratic presidential nominee Hillary Clinton in 2016 but joined President Donald Trump’s economic advisory team after the president’s inauguration. Musk’s tenure only lasted a few months, however: he left the team in June 2017 over the administration’s policies regarding climate change.

Real Clear Politics’ latest aggregate of polls shows Yang with an average of 1.3 percent support in the polls.
