President Trump posted a series of tweets on Saturday.

President Trump declared that "when people come into our Country illegally, they will be DEPORTED!" 
He made the statement on Twitter Saturday morning after writing in a separate post: "The people that Ice will apprehend have already been ordered to be deported. This means that they have run from the law and run from the courts. These are people that are supposed to go back to their home country. They broke the law by coming into the country, & now by staying." 
The president's warnings come just one day before U.S. Immigration and Customs Enforcement agents are reportedly planning to conduct raids aimed at capturing families with outstanding deportation orders. 
According to the Washington Post, up to 10 major U.S. cities with large immigrant populations, including Miami and Los Angeles, may be targeted, with as many as 2,000 families possibly detained from the operation.
That said, acting Department of Homeland Security Secretary Kevin McAleenan has reportedly been cautious about the scope of the operation in the wake of controversies like family separations.
