Twitter co-founder is among latest major donors to the Obama Foundation

The Chicago Tribune reports:

The billionaire co-founder of Twitter is among the new donors to the Obama Foundation, which on Thursday made public the names of almost two dozen major donors from the first three months of the year.

Evan Williams and his wife, Sara Morishige, gave between $750,000 and $1 million to the foundation. Forbes put Williams' net worth as $1.29 billion.

Michael Sacks and his wife, Cari, of Highland Park, were one of two couples who have given money in the past and whose overall gifts now exceed $1 million. Sacks is chairman and CEO of GCM Grosvenor Capital Management, a former top fundraiser for Obama and a close ally of Mayor Rahm Emanuel.

No word yet on when Obama might join the board of Twitter.
