WASHINGTON (AP) — The Republican-controlled House voted Thursday to resume the deportation of hundreds of thousands of immigrants brought illegally to the United States as children, a largely symbolic move in the first immigration-related vote in either chamber of Congress this year and a measure of the daunting challenge facing supporters of a sweeping overhaul of existing law on the subject.

The party-line vote of 224-201 was aimed at blocking implementation of President Barack Obama's 2012 election-year order to stop deportations of many so-called DREAM Act individuals. Democrats on the House floor reacted with boos when the provision was added to a routine spending bill for the Department of Homeland Security.

The administration has threatened to veto the overall legislation on budgetary grounds. It nevertheless stood as a stark warning from conservatives who dominate the ranks of the Republican House majority about attempts in the Senate to grant a chance at citizenship to an estimated 11 million immigrants residing in the country illegally.
