Pressure is mounting on CEOs to step down from President Donald Trump's American Manufacturing Council, after the leaders of Merck (MRK) , Under Armour (UAA) and Intel (INTC) quit Monday.

The CEOs quit over Trump's lukewarm response to racist violence over the weekend in Charlottesville. While General Electric (GE) said the company has "no tolerance for hate, bigotry or racism" and condemned "violent extremism," but confirmed that CEO Jeff Immelt would remain on the manufacturing council.

A Twitter campaign has been launched calling for a boycott of products from the companies whose CEOs still sit on the council. Users were calling for a boycott of General Electric, Whirlpool (WHR) and Johnson & Johnson (JNJ) .

The hashtag #SoupNazi, referring to the infamous scene from Seinfeld, was trending alongside calls for Campbell Soup (CPB) CEO Denise Morrison to step down from the council.

Campbell's CEO is on Trump's advisory council. Until Bannon's fired, staying on that council means brand risk of being called #SoupNazis https://t.co/X9MXd5UTbz

Campbell Soup , Whirlpool , Nucor (NUE) and International Paper released statements during Monday condemning hate groups in Charlottesville. They also confirmed that their CEOs would remain on Trump's manufacturing advisory council.

Dell Technologies spokeswoman Lauren Lee confirmed Michael Dell, who sits on the manufacturing council, will not change his relationship with Trump. "While we would not comment on any member's personal decision, there's no change in Dell engaging with the Trump administration and governments around the world to share our perspective on policy issues that affect our company, our customers and our employees," she said in an email.
