White House planning new immigration steps

US President Donald Trump was expected to unveil new measures on immigration as early as this week in the name of keeping US citizens safe, with a top aide insisting he did not overstep his authority with his controversial travel ban.

With the ban now frozen by a federal appeals court pending further legal review, Trump is "considering and pursuing all options", presidential aide Stephen Miller told Fox News Sunday.

The White House could either file an emergency appeal to the Supreme Court, defend the merits of the order in lower courts or issue a new executive order. The last option was floated by Trump himself on Friday.
