President Obama says he will use executive action to address problems with the nation’s immigration system.

Speaking in the White House Rose Garden Monday, Obama announced plans to act unilaterally and criticized Republicans in the House for failing to act on a comprehensive overhaul. Citing what he called a humanitarian crisis on the border, Obama said he will direct the Secretary of Homeland Security and the Attorney General to move enforcement assets from the interior of the U.S. to the border. Further, he said, his Cabinet will meet to decide on recommendations for further action by the end of the summer.

Obama’s announcement comes a week after House Speaker John Boehner announced plans to sue the president, alleging that his frequent executive actions are unconstitutional.
