According to Fox News:
Gene Sperling, director of the White House's national economic council, said today at an official meeting that "we need a global minimum tax":
“We need a global minimum tax so that people have the assurance that nobody is escaping doing their fair share as part of a race to the bottom or having our tax code actually subsidized and facilitate people moving their funds to tax havens," Sperling said.
I wrote a mechanism to deliver such a tax about five years ago but the time did not seem right.
I'll drag it out and dust it down again soon.
