Republican presidential candidate Donald Trump has called for a "total and complete" halt to Muslims entering the US, in the wake of the deadly California shootings.
He said that polling showed a "hatred" by Muslims towards Americans that could put the nation at risk.
The border shutdown should remain "until our country's representatives can figure out what is going on".
The White House swiftly criticized Trump's statement as "un-American".
A statement said it is contrary to US values and its national security interests.
