President Donald Trump promotes himself as a fighter for business development and support, but many leading US businessmen openly oppose the administration of the White House and its policies in the fields of immigration and environmental security.

Sheryl Sandberg, Facebook COO

Sheryl Sandberg came out against President Trump's immigration ban in a post saying that the executive order defies "the heart and values that define the best of our nation." "Families have been separated," Sandberg wrote on Facebook. "Frightened children have been detained in airports without their parents. People seeking refuge have been turned away and sent back to the danger they just managed to flee. This is not how it should be in America."

She also expressed negative opinions about other decisions of the Trump's administration.

Kevin Plank, Under Armour CEO

During an interview on CNBC's “Fast Money Halftime Report” on Tuesday, Under Armour CEO Kevin Plank stated that he was a big fan of President Donald Trump and that he believes Trump is “a real asset for the country.” Plank's remarks come after his January meeting at the White House which included other major business leaders to discuss the future of manufacturing and job creation in America. His opinion received a slew of negative responses from people who disagree with President Trump's policies. However, later Plank took out a full-page ad in the Baltimore Sun to denounce Trump's travel ban for citizens of several Muslim-majority nations.

Travis Kalanick, Uber CEO

Uber CEO Travis Kalanick leaved President Trump's advisory council, after the Independent Drivers Guild launched a petition calling for Kalanick's resignation, in support of immigrants.

Elon Musk, Tesla and SpaceX CEO

Tesla and SpaceX CEO Elon Musk said that he would have "no choice" but to leave Trump's advisory councils (an economic advisory board and the Manufacturing Jobs Initiative). He chose to remain on Trump's two councils in the wake of criticism related to the President's proposed immigration ban, but drew the line when it came to breaking the Paris Agreement. Experts believe that Mask tried to influence the president's rhetoric in matters of ecology and environmental pollution.

Bob Iger, Disney CEO

Disney CEO Bob Iger has quit President Donald Trump's business advisory council over Trump's decision to pull the US out of the Paris climate agreement.

"As a matter of principle, I've resigned from the President's Council over the #ParisAgreement withdrawal," Iger tweeted. Disney gave this longer statement from Iger: "Protecting our planet and driving economic growth are critical to our future, and they aren't mutually exclusive. I deeply disagree with the decision to withdraw from the Paris Agreement and, as a matter of principle, I've resigned from the president's advisory council."

Peter Thiel, PayPal CEO

Peter Thiel has always been considered an ardent supporter of the policies and views of Donald Trump. Thiel even supported his candidacy at the Republican National Convention. However, taking into consideration the public discontent with the policy of the new US president, the founder of PayPal changed his mind. He has distanced himself from the president in multiple private conversations, describing at different points an “incompetent” administration, and one that may well end in “disaster.”

Brian Krzanich, Intel CEO

Intel CEO Brian Krzanich released a statement saying he too was stepping down from the council. "Earlier today, I tendered my resignation from the American Manufacturing Council," Krzanich wrote. "I resigned to call attention to the serious harm our divided political climate is causing to critical issues, including the serious need to address the decline of American manufacturing. Politics and political agendas have sidelined the important mission of rebuilding America's manufacturing base."

Richard Trumka, AFL-CIO President

Richard Trumka, the president of the AFL-CIO, said in a statement he is leaving President Donald Trump's manufacturing council due to the president's response to the violence in Charlottesville. "We cannot sit on a council for a President who tolerates bigotry and domestic terrorism," Trumka said in a statement. "President Trump's remarks today repudiate his forced remarks yesterday about the KKK and neo-Nazis. We must resign on behalf of America's working people, who reject all notions of legitimacy of these bigoted groups."
