The House voted on Thursday to embrace the legal challenge to President Barack Obama's actions on immigration in an election-year fight over executive authority and the 11 million immigrants living in the United States illegally that has roiled the Republican Party. Republicans who hold a commanding majority cast the issue as Obama exceeding his constitutional authority in unilaterally expanding programs for immigrants. They prevailed on a 234-186 vote that authorizes Speaker Paul Ryan, R-Wis., to file a friend-of-the-court brief in the case of United States v. Texas.
