After President Donald Trump signed an executive order restricting immigration from seven predominantly Muslim nations, SpaceX founder and CEO Elon Musk turned to Twitter to voice his frustrations.
The billionaire entrepreneur usually abstains from making his political opinions known, especially on social media, with the exception of the occasional shout-out to climate science. However, it seems that Trump's anti-immigrant sentiment struck a nerve this time.
Trump's executive order, which he signed Friday (Jan. 27), suspends immigration of refugees from war-torn countries around the world for 120 days while indefinitely barring everyone in Syria from entering the United States regardless of immigration status. People in six additional countries with Muslim-majority populations are also banned from the U.S. for 90 days.
On Saturday (Jan. 28), one day after Trump signed the executive order, Musk began to tweet his thoughts on the new immigration restrictions. He wrote that the executive action "is not the best way to address the country's challenges," and pointed out that many people are unfairly affected by the policy.
To combat the new order without outright rejecting it, Musk has asked his Twitter followers to read the full text of the executive order and come up with ideas to amend it. While several of his followers called for a repeal, Musk — who became an adviser to Trump in December, feels that an amendment would be more feasible.
