CLEVELAND, Ohio - Cleveland Clinic CEO Toby Cosgrove plans to remain an advisor to President Donald Trump, even as a fourth business executive resigns from the president's advisory team.

Pharmaceutical giant Merck & Co. Inc. CEO Kenneth Frazier on Monday morning announced via Twitter his resignation from Trump's Manufacturing Jobs Initiative, one of the president's two advisory groups of business executives, after the president for two days failed to denounce white nationalism in the wake of the violent weekend rally in Charlottesville, Virginia.

There are "no changes" to Cosgrove's advisory role, Clinic spokeswoman Eileen Sheil said Monday. The Clinic's top executive serves on Trump's Strategic and Policy Forum.

"Dr. Cosgrove believes that it's important to be able to provide input at the highest level of government on healthcare matters," Sheil said in an email. There hasn't been a meeting of the Strategic and Policy Forum since April, and there aren't any future meetings scheduled, Sheil said.

Cosgrove's position remains much the same as it did in January, when he first assumed the advisory post. At that time, Cosgrove told The Plain Dealer, "He is the president of the United States. I think it's important that we give him the best input that we can. I wouldn't care if he's a Republican or a Democrat or Green."

Cosgrove said in May he plans to remain an advisor to the president even after he steps down as CEO of the Clinic later this year.

Since January, four executives, including Frazier, have opted to resign from Trump's advisory councils in response to the administration's actions. Tesla CEO Elon Musk and Disney CEO Robert Iger in June resigned after the president said he was going to withdraw from the Paris climate agreement. Uber CEO Travis Kalanick resigned in February after Trump announced his immigration executive order, known as the "Muslim ban."

"America's leaders must honor our fundamental values by clearly rejecting expressions of hatred, bigotry and group supremacy, which run counter to the American ideal that all people are created equal," wrote Frazier, who is one of only a handful of black CEOs of major corporations in the U.S. "As CEO of Merck and as a matter of personal conscience, I feel a responsibility to take a stand against intolerance and extremism."

The Cleveland Clinic has been under pressure since January to cut ties with the Trump administration. In January, the Clinic received criticism over its decision to hold a February fundraiser for the Cleveland Clinic Florida at Trump's Mar-a-Lago resort in Palm Beach, Florida, weeks after the administration's executive order on immigration that initially kept the Cleveland Clinic's Dr. Suha Abushamma from re-entering the country.

And in recent weeks, a group of doctors and medical students, among others, called for the Clinic to relocate from Mar-a-Lago its 2018 fundraiser for its Florida site.

The group said "holding a fundraiser at Mar-a-Lago is unacceptable because it symbolically and financially supports a politician actively working to decrease access to healthcare and cut billions of dollars in research funding from the National Institutes of Health budget." The Clinic, however, plans to keep the event at Mar-a-Lago in 2018.
