WASHINGTON — President Trump on Jan. 25 began a sweeping crackdown on illegal immigration, ordering the immediate construction of a border wall with Mexico and aggressive efforts to find and deport unauthorized immigrants. He planned additional actions to cut back on legal immigration, including barring Syrian refugees from entering the United States.
At the headquarters of the Department of Homeland Security, Mr. Trump signed a pair of executive orders that paved the way for a border wall and called for a newly expanded force to sweep up immigrants who are in the country illegally. He revived programs that allow the federal government to work with local and state law enforcement agencies to arrest and detain unauthorized immigrants with criminal records and to share information to help track and deport them.
