South Bend Mayor Pete Buttigieg is set to attend a fundraiser with a top Uber executive just weeks after expressing solidarity for drivers protesting the ridesharing company.

The Indiana Democrat is one of 14 presidential candidates who will descend on San Francisco this weekend for the California Democratic Party State Convention. Between attending an SEIU California Democratic Delegate breakfast on Saturday morning and addressing convention goers later that afternoon, he will headline a fundraiser in Oakland hosted, in part, by Uber executive Chelsea Kohler, the rideshare companys director of product communications.

It is a dissonant move for a candidate who fewer than three weeks ago voiced his support for striking Uber drivers demanding an end to pay cuts and a drivers bill of rights ahead of the ridesharing companys initial public offering on Wall Street.

Im standing in solidarity with @_drivers_united and all those striking across the country today for livable wages, more job security, and regulated fares, Buttigieg tweeted on May 8, the day of the international rideshare strike.We must raise the labor standards in this country.

Buttigiegs presence at the fundraiser illustrates the fraught position he occupies as one of the most tech-friendly candidates in a primary campaign where candidates are trying to demonstrate their pro-worker bona fides. He has deep ties to Silicon Valley heavyweights and even went to college with tech titans such as Facebook co-founder Chris Hughes, who has long supported Buttigiegs political career. Yet Buttigieg is also a ubiquitous presence alongside striking workers at picket lines. In April, he backed workers employed by the Stop & Shop grocery chain in Malden, Mass., and recently cut a video supporting McDonalds employees fight for a $15 minimum wage and a union.

Buttigiegs support for striking Uber drivers seemed to echo those past efforts. Among other demands, the Drivers Bill of Rights would include Uber and Lyfts recognition of our independent, driver-led organization, to negotiate on behalf of drivers. On his policy page, Buttigieg advocates for a new Wagner Act to support the role of organized labor and defend the right of workers to organize.

Our nations middle class was built by organized labor, and rising attacks on labor have led to the middle class becoming more and more vulnerable, according to the page. Buttigieg also says he supports a $15 minimum wage.

But Buttigieg also hasnt gone quite as far as his fellow nominees in coming down hard on Silicon Valley, chiefly Sen. Elizabeth Warren (D-MA), who has proposed breaking up tech giants such as Google. At a New Hampshire CNN town hall in April, Buttigieg said that antitrust law "as we know it has begun to hit its limits with regulating big tech companies. Its not designed to handle some of these tech companies where theres actually no price at all. The product is made free, or at least its free on its face. Weve learned in part because of the way our data are used by these companies that nothing is actually free.

Chris Meagher, Buttigiegs national press secretary, declined to comment. But an organizer with the Los Angeles-based drivers association told The Daily Beast that the candidates decision to fundraise with an Uber executive was untenable with his support for the contracted drivers.

We appreciate Pete Buttigiegs support, and this is an instance where there are two clearly opposing sides and he must pick one, emailed Brian Dolber. Passenger fares either go to the hardworking drivers or the multi-billion dollar companiesand right now Uber/Lyft are regularly taking 50%+ of what the passenger pays while countless drivers are homeless or living in poverty. Standing with drivers, means standing against the executives who have been ruthlessly slashing driver pay year after year.

Other tech executives will be at the Saturday fundraiser for the South Bend Mayor, including Chris Cox, Facebooks former chief product officer; Scott Kohler, Googles corporate counsel; and Clay Bavor, Googles vice president of virtual and augmented reality. Tickets for the event run from $25 to $2,800.

Dolber, who is also an assistant professor of communication at California State University San Marcos, said the fault line exposed in this case could be a harbinger of whats to come for the Democrats in 2020.

Worker movements and popular criticism of Silicon Valley suggest that the Democratic Party's long standing connections to Big Tech may prove to be a problem for their base, Dolber said. Political candidates will have to reconsider a strategy that triangulates between impoverished workers and billionaire bosses. The conversation around the gig economy and inequality, as well as algorithmic management, surveillance, and automation is shifting the political terrain.
