WASHINGTON (USA TODAY) -- The fallout from President Trump's response to the Charlottesville tragedy escalated Wednesday as more prominent CEOs quit advising the White House on economic matters and Trump disbanded his manufacturing and business policy councils.

"Rather than putting pressure on the businesspeople of the Manufacturing Council & Strategy & Policy Forum, I am ending both. Thank you all!," Trump tweeted.

Campbell Soup CEO Denise Morrison and 3M CEO Inge Thulin Wednesday joined a growing list of American chief executives who are leaving the president's manufacturing job council, an advisory group the White House formed this year.

Pressure from the business community has been intensifying this week following Trump's widely criticized response to violence that erupted after a neo-Nazi rally in Charlottesville, Virginia, over the weekend.

On Monday, Merck CEO Ken Frazier became the first major American chief executive to speak out against Trump's response, quitting the manufacturing council as "a matter of personal conscience."
