Donald Trump signed the Laken Riley Act on Wednesday as the president approves a series of initiatives meant to tackle his goal of curbing illegal immigration.

The legislation will require immigration officers to detain immigrants who are in the U.S. illegally when they're accused of lower-level crimes like shoplifting.

President Donald Trump said Wednesday that he is directing the opening of a detention center at Guantanamo Bay to hold up to 30,000 immigrants who are living illegally in the United States. People who are in the United States illegally and are accused of theft and violent crimes would have to be detained and potentially deported even before a conviction.
