What people are afraid that Trump might do Obama already did.
President Obama has approved military operations and bombings in Iraq, Afghanistan, Pakistan, Somalia, Yemen, Libya and Syria. The Bureau of Investigative Journalism (BIJ) estimates the Obama administration has launched more than 390 drone strikes in five years across Pakistan, Yemen and Somalia – eight times as many approved during the entire Bush Presidency. President Barack Obama has often been referred to by immigration groups as the "Deporter in Chief." Between 2009 and 2015 his administration has removed more than 2.5 million people through immigration orders, which doesn’t include the number of people who "self-deported" or were turned away and/or returned to their home country at the border by U.S. Customs and Border Protection.
According to governmental data, the Obama administration has deported more people than any other president's administration in history. In fact, they have deported more than the sum of all the presidents of the 20th century.
President George W. Bush's administration deported just over two million during his time in office; and Obama’s numbers don’t reflect his last year in office, for which data is not yet available.
