““Speaking on ABC’s “This Week,’’ Pfeiffer said Obama has no choice but to act on his own because of Congress’s ‘‘failure to fix the immigration system’’ and to provide extra money to deal with Central American children crossing the US-Mexico border. House Republicans on Friday approved a bill to address the problem of unattended children crossing the Mexican border. The measure would allocate $694 million for border security efforts, including $35 million for the National Guard, and also clear the way for eventual deportation of more than 700,000 immigrants brought here illegally as children. The Senate shelved its own bill on emergency border funds, which means no final congressional action will occur until lawmakers return from their five-week summer break.””
