Democratic presidential candidate Elizabeth Warren responded to a report that Facebook CEO Mark Zuckerberg has quietly recommended potential hires to Pete Buttigieg’s campaign.

Warren said that she believed Facebook has “too much political power” and echoed her proposal to break up major tech companies but avoided criticizing Buttigieg by name.

Earlier this year, Zuckerberg sent multiple emails to Mike Schmuhl, Buttigieg’s campaign manager, with names of individuals that he might consider hiring, campaign spokesman Chris Meagher confirmed. Priscilla Chan, Zuckerberg’s wife, also sent multiple emails to Schmuhl with staff recommendations. Ultimately, two of the people recommended were hired.

The emails between Zuckerberg and Buttigieg have come to light as Zuckerberg faces unrelenting attacks from politicians from both parties over such issues as misinformation, privacy, election meddling and bias. Zuckerberg is scheduled to testify Wednesday before the House Financial Services Committee on Facebook’s impact on the financial services and housing sectors.
