However, Vox, a news media website, called out that Donald Trump had made an impossible promise.

According to a Vox article, US Immigration and Customs Enforcement (ICE) estimated that there were only about 1.94 million removable criminal illegal immigrants currently living in the US.

Nevertheless, Khansari stated that despite Trump may not seem to fully understand the immigration situation of his country, his newly appointed advisors do, so he worried the anti-immigration remarks surrounding Trump would soon become policies.

As of now, Immigration and Customs Enforcement or commonly known as ICE is the main force of handling immigration enforcement matters in the United States.

ICE has the power to deport any non-citizen immigrants who violate the term of their stay, such as committing certain types of crimes, or simply failing to advise authorities of their change of address.

Except of enforcing operations of ICE, since from 1979, LAPD did not handed any undocumented immigrant arrested for low-level offense to federal agents for deportation.

While the exact number of undocumented immigrants in the US is unknown, the US Department of Homeland Security estimated that about 11.4 million unauthorized immigrants lived in the country in 2012.
