Corporate America has joined the protest of President Donald Trump’s immigration ban after masses around the country took to airports and other public spaces to demonstrate.

The protests came after Trump on Friday signed an executive order barring Syrian refugees from entering the U.S., blocked citizens of seven majority-Muslim countries from entering the country for 90 days and suspended all refugee admission for 120 days.
