Despite her attacks against South Bend, Indiana, Mayor Pete Buttigieg's ties with McKinsey & Co., Elizabeth Warren has received the second-most amount of money from employees of the management consulting firm, according to a review of Federal Election Commission documents.

Since she announced her candidacy in February, the Massachusetts senator, 70, has received $10,098.85 from those who work or have worked at McKinsey, compared to Buttigieg, who has raised $17,280. The rest of the field is in the four-figures or less, with Minnesota Sen. Amy Klobuchar raising $31.

Buttigieg has come under fire from both Warren and left-wing members of the Democratic Party over his history working for the firm for nearly three years, starting in 2007. For months, Warren demanded Buttigieg release a detailing of his work and clients. Warren and other McKinsey critics point to controversies that have ensnared companies like the management consulting firm, including advising governments in Saudi Arabia and China.

Earlier this month, Buttigieg's campaign negotiated an agreement with McKinsey to publish his former client list.

The Washington Examiner has reported that Warren's own ties with the firm go back decades as well, starting with her time at Harvard Law School where she hired the firm to implement a " long-term development" plan at the cost of $800,000 to $1 million. That project was broadly criticized by students at the time.

Towards the end of that contract, Warren's daughter, Amelia Warren Tyagi, was finishing her work with McKinsey. From 1996 to 1999, Tyagi worked as an engagement manager and focused on healthcare, education, finance, and pharmaceuticals.

Starting in 2011, as head of the Consumer Financial Protection Bureau, Warren hired several McKinsey alums for senior positions at the agency.

At the conclusion of the third-quarter, Warren announced the second-largest fundraising hauls of the 2020 field, at nearly $25 million. That sum put her above former Vice President Joe Biden, who raised $15.3 million, Buttigieg, at $19.1 million, and behind Vermont Sen. Bernie Sanders, who raised $25.3 million.
