WASHINGTON (Reuters) - A White House official on Sunday attacked a U.S. court ruling that blocked President Donald Trump's executive order on immigration as a "judicial usurpation of power" and said the administration was considering a range of options, including a new order.

Sustained criticism of the judiciary from the White House comes amid concern among Democrats and legal scholars over Trump's view of the constitutional principle of judicial independence as the administration seeks to overcome legal setbacks to its travel ban issued on Jan. 27.
