Brad Anderson has stepped down from four more boards of directors following news that he'd given money to an organization that produced anti-Muslim videos. Minnesota Public Radio, General Mills, Waste Management Inc. and Carlson all confirmed that Anderson had resigned from their boards.
According to filings with the Securities and Exchange Commission, Anderson resigned from the General Mills and Waste Management boards. MPR confirmed that Anderson has submitted a letter of resignation. Carlson also confirmed Tuesday that Anderson resigned from that company's board.
Anderson, the former Best Buy CEO, came under scrutiny after it was revealed he had donated $25,000 to Secure America Now, a political group that produced several anti-Muslim videos.
He told MPR News last week that he gave to the group in support of the security of Israel and had no idea the group would make such videos. He said he wouldn't have given money to the group if he had known.
The revelation led to calls for Anderson's resignation from several boards on which he serves from the Council on American Islamic Relations Minnesota Chapter.
In a statement, MPR's board chair David Murphy said the board is saddened to have received Anderson's letter of resignation and that they did not request the letter.
Murphy said he's grateful for all that Anderson invested in the mission and public service of the organization.
He also wrote that MPR and its parent company, APMG, "share a commitment to the values of respect, diversity and inclusion of all people."
Anderson resigned from the Mayo Clinic board last week.
