Boehner: Obama 'damaging presidency'

Republican Speaker of the House John Boehner had harsh words for Democratic US President Barack Obama's executive action on immigration.

The conservative leader has challenged Mr Obama on going beyond the scope of his authority in the unilateral action.

"The president has taken actions that he himself has said are those of a king or an emperor, not an American president," Mr Boehner said.

"He's damaging the presidency itself."
