Amazon will select a location for its second headquarters by the end of the year, CEO Jeff Bezos said Thursday night.
Demonising the media and calling them "the enemies of the people" is risky, Bezos said.
Within this, the Day 1 Families Fund will support existing non-profits that offer shelter and food to young homeless families.
It's not yet known what his preschools will look like except that they will be based on the teaching philosophy of Maria Montessori, which focuses on play-based learning that caters to individuality and social-emotional development.
In 2016, Bezos was asked if he planned to pursue philanthropy like Gates has. It is a contrast to the long view that Bezos has preached at Amazon and Blue Origin, the space-travel technology company he has been funding with $1 billion a year through the sale of Amazon stock. "Never have I been more comfortable at an Amazon board meeting!"
Mr Bezos - reportedly worth more than $164bn - has faced criticism for not doing more philanthropic work.
Amazon has said the senator's statements about the company are "inaccurate and misleading". City leaders quickly rescinded the levy.
Employees at Amazon followed Jeff Bezos example and also started 'PJammin'. "But we're going to make a final pitch". Bezos was in town with his parents, who run the Bezos Family Foundation.
"He's a pretty wonderful neighbour, him and [his wife] MacKenzie", said Mary's Place director Marty Hartman. Since March 2016, Amazon customers have also been able to order items from the Mary's Place's wishlist on the site, such as diapers and socks.
Where a "network" of Bezos preschools is concerned, we should be especially sceptical.
And earlier this year, under pressure from Amazon and other large employers, Seattle's city council repealed an employee head tax that would have funded housing and services for the homeless.
"But it is really risky to demonise the media".
Bezos solicited ideas on Twitter previous year for ways to donate some of his wealth.
Last year, he donated $33 million to fund scholarship for "dreamers", the name given to undocumented children of immigrants who face legal obstacles in attending college or university.
And he also hasn't signed The Giving Pledge, an initiative created by the Gateses and Buffet that encourages billionaires to give away the majority of their wealth to philanthropy.
