Strib posted a recent report about Mayor Carter's endorsing the effort in St. Paul, and a current report of Twitter's founder presently putting a gift of fifteen million dollars more into the effort.
MinnPost's Dec. 8, 2020, Glean summarized:
Twitter CEO Jack Dorsey is donating $15 million to programs across the country, the Mayors for a Guaranteed Income group announced Tuesday. The more than two dozen mayors participating in the group, including St. Paul Mayor Melvin Carter, will each receive a minimum of $500,000 to grow or sustain their programs. This builds on Dorsey’s initial $3 million donation last summer.”
