Top CEOs plan 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.
