With the White House touting a "year of action" aimed at circumventing a gridlocked Congress, House Speaker John Boehner is now promising to push the GOP-led House to sue President Obama over his use of executive actions.
But what does suing the president actually mean, and what particular actions do House Republicans think necessitate a legal challenge? What can they accomplish?
Boehner paints the move as part of a constitutional struggle between the legislative and executive branches, saying that Obama has exceeded his presidential power by issuing orders on issues like the environment, paid family leave, health care and LGBT rights.
"I believe the House must act as an institution to defend the constitutional principles at stake and to protect our system of government and our economy from continued executive abuse," he said Wednesday.
