Top CEOsplan to get dramatically tougher on state legislators over proposed new restrictions on voting.

Driving the news: After a weekend Zoom summit, the CEOs are threatening to withhold campaign contributions — and to punish states by yanking investments in factories, stadiums and other lucrative projects.

The call included a long list of business luminaries, including James Murdoch, Ken Chenault, Ken Frazier, LinkedIn co-founder Reid Hoffman, Levi Strauss CEO Chip Bergh, Atlanta Falcons owner Arthur Blank, and executives of Delta, United and American Airlines.

Saturday's historic Zoom summit was organized by Professor Jeffrey Sonnenfeld of Yale School of Management, who told me the execs "fortified each other": "There was no sense of fear."
