(WASHINGTON) — The Justice Department is looking for more ways to deny coveted federal grant money to so-called sanctuary cities. Attorney General Jeff Sessions said in a department memorandum Monday that the department may “tailor grants to promote a lawful system of immigration.” That suggests officials could seek ways to withhold money from communities that refuse to honor detainer requests from federal immigration authorities. A judge in April blocked President Donald Trump’s attempt to withhold funding from some localities, saying the president doesn’t have the authority to attach new conditions to spending by Congress.
