The Sherwood Foundation (SF) is a Omaha, Nebraska-based 501(c)(3) grantmaking foundation founded and chaired by Susan A. Buffet, the daughter of billionaire investor and left-wing donor Warren Buffet. 1 2 Sherwood Foundation assets were $376,758,547 in 2018 and the foundation provided $147,538,375 in grants in 2018. 3

Sherwood Foundation focuses most of its contributions on Nebraska-based social, cultural, community, and educational organizations but also exhibits a left-leaning political orientation. SF states that its grantmaking promotes left-of-center social policy and expects recipients of SF donations to have similar values, specifically support for abortion. 4

The SF donated tens of thousands to the Clinton Foundation, affiliated with former US President Bill Clinton and 2016 Democratic Party presidential nominee Hillary Clinton. SF donated $1 million to support anti-gun-rights protests in 2018, and contributes to social liberal groups including Planned Parenthood and the American Civil Liberties Union. 5 6

Sherwood Foundation supports the OpenSky Policy Institute, which focuses on promoting left-of-center budget and tax policies in the state of Nebraska. The OpenSky Policy Institute is a member of the State Priorities Partnership, a coalition of left-of-center, state-based advocacy groups active in 43 states. 7

The SF contributed over $200,000 in 2018 to Nebraskans for Civic Reform’s (now Civic Nebraska) efforts to allow convicted felons in Nebraska to be immediately eligible to vote upon release from prison. Nebraska law currently requires released felons to wait two years before having their voting rights restored. 8 9


The Sherwood Foundation was founded in 199910 by Susan A. Buffett as the Susan A. Buffet Foundation with a donation of $1 billion in Berkshire Hathaway stock from her father, Warren Buffett. 11  In 2006 the foundation received another $1 billion in Berkshire Hathaway stock donated by Warren Buffett. 12 The foundation moved to its current Omaha offices in 2017. 13

In November 2022, according to the Securities and Exchange Commission, the Sherwood Foundation received 300,000 Class B shares in Berkshire Hathaway stock from Warren Buffett, part of $750 million in Hathaway stock that he donated that month to Sherwood as well as several foundations associated with Buffett including the Susan Thompson Buffett Foundation, the Howard G. Buffett Foundation and the NoVo Foundation. 14 15


Susan A. Buffett, Chair

In addition to chairing the SF, Susan A. Buffet is on numerous other nonprofit boards and commissions, including the Susan Thompson Buffett Foundation, the Buffett Early Childhood Fund, and ONE (a national anti-poverty nonprofit). She is also a member of the Omaha Airport Authority. 16

Buffet, like her father, donates substantial sums to the Democratic Party and its candidates. 17 In 2016, Buffett was listed by the Center for Responsive Politics as one of “1,129 elites (that) are directing at least $112,300,000 for Clinton’s election efforts — money that has gone into the coffers of her campaign as well as the Democratic National Committee.” 18

Putnam is managing attorney at the Omaha, Nebraska-based law firm, Baird Holm LLP. 19

Allen Greenberg, Member

Greenberg is the former husband of Susan A. Buffett, from whom he was divorced in 1995. He is currently an attorney for Public Citizen, a liberal 501(c)(4) lobbying and advocacy organization created by left-wing activist and former Green Party presidential candidate Ralph Nader. Greenberg is also president of the Susan Thompson Buffett Foundation, another Buffett-family controlled grantmaking organization. 20

Wallace Weitz, Member

Weitz is Chief Financial Officer of Oklahoma-based Weitz Investment Management and the founder of the private, charitable Weitz Family Foundation. 2122 Weitz has donated tens of thousands to the Democratic Party and Democratic Party candidates for office. 23

In 2008, Weitz and Warren Buffett were the two largest donors to Nebraskans United, a ballot question committee established to protect Nebraska government’s use of racial-preference policies in government employment, contracting and public college admissions. 24 Nebraskans United formed to oppose the Nebraska Civil Rights Initiative, also known as Initiative 424, which collected signatures to place a proposed state constitutional amendment on the 2008 election ballot. The proposal would prohibit Nebraska political subdivisions from discriminating against, or giving preferential treatment to, any person or group based on race, sex, color, ethnicity or national origin. 25

Weitz contributed $50,000 to Nebraskans United’s unsuccessful efforts to defeat Initiative 424 and maintain Nebraska governments’ ability to use affirmative action programs that grant preferences based on race and gender. Nebraskans United allegedly used controversial “blocking” tactics to make it difficult for Initiative 424 petitioners to gather signatures for the proposal. Nebraskans United’s paid advertisements discouraging citizens from supporting the initiative were criticized as deceptive. 26

Wilhelm is executive director of Girls, Inc. – a Nebraska-based nonprofit that helps girls. 27 She is a donor to Hillary Clinton’s 2016 presidential campaign28 and has arranged prominent, primarily left-aligned speakers at Girls, Inc. functions, including former Presidents Bill Clinton and Barack Obama, former First Ladies Michelle Obama and Hillary Clinton, and Chelsea Clinton. 29
