The Trump administration is shifting $271 million earmarked for disaster aid and cyber security to pay for immigration-related facilities, the U.S. Department of Homeland Security and a leading congressional Democrat said on Tuesday.

The money, which was also set aside for the U.S. Coast Guard, will be used to pay for detention facilities and courts for migrants arriving at the U.S.-Mexico border. DHS officials say they have been overwhelmed by a surge of asylum-seeking migrants who are fleeing violence and poverty in Central America.

The Trump administration is seeking to circumvent Congress and move money originally designated for other programs. This will allow the administration to continue to house immigrants arriving at the border, part of President Donald Trump's promise not to "catch and release" migrants and allow them to await hearings outside of custody.
