The Trump administration's detention facilities that house migrants who were apprehended while crossing the border illegally appear on Wikipedia's list of internment and concentration camps.
While previous administrations have also used detention facilities, the Trump administration took the extra step of instituting a "zero-tolerance" policy of separating parents from their children and have disallowed exceptions that the Bush and Obama administrations permitted.
The Wikipedia page is titled "Internment " and encapsulates both internment camps as well as concentration camps.
The page uses the American Heritage Dictionary to define a concentration camp as "a camp where persons are confined, usually without hearings and typically under harsh conditions, often as a result of their membership in a group which the government has identified as dangerous or undesirable." Additionally, internment is defined as "the imprisonment of people, commonly in large groups, without charges or intent to file charges, and thus no trial."
The page lists 15 examples of either internment or concentration camps, and the most recent one reads, "Trump administration migrant detentions as part of immigration detention in the United States (2018-president)." It also lists Guantanamo Bay as a "detention camp" that remained in place during the Bush, Obama, and Trump administrations.
