Stephen Miller: 'Trump will protect his national emergency declaration'

The total of $8 billion to be directed to wall construction is far less than the estimated cost of a wall along the entire length of the US-Mexico border, which is estimated at $25 billion or even higher.

Stephen Miller appeared unhinged on "Fox News Sunday" over President Trump's national emergency declaration in an often-contentious interview with the White House senior advisor.

Trump on Friday invoked emergency powers invested in the president by the 1976 National Emergencies Act to justify repurposing federal funds to pay for a wall between the USA and Mexico, one of his signature 2016 campaign promises that is opposed by most Democrats. This step of President Donald Trump is to repurpose funds from various other parts of the government so that he can go forth with his plan of building the border wall.

Under a 1976 law, Trump's emergency powers could allow him to redirect money appropriated by Congress to build the wall, but the Democrats have said they will not let that happen. But it is unclear whether there are enough of them to vote against the president (and his base) to override a veto. But Trump's declaration goes beyond previous emergencies in shifting money after Congress blocked his funding request for the wall, which will likely factor in legal challenges. "I could do the wall over a longer period of time", Trump said Friday during a hyperbole-filled Rose Garden speech.

Democratic Congressman Adam Schiff, chairman of the House Intelligence Committee, told CNN, "If we give away, if we surrender the power of the purse... there will be little check and no balance left".

Miller rejected the assertion that a wall would not be effective against the arrival of undocumented migrants, which has been declining for more than two decades, or contribute to the interception of illegal drugs, which government figures show overwhelmingly enter the U.S. through monitored ports and border crossings. Trump ally Jim Jordan told ABC that he believes there are enough GOP votes to prevent the supermajorities required to override a veto.

"Donald Trump, we'll see you in court", Newsom said, according to NPR.

California and other states are expected to sue the Trump administration to block Trump's move.

The Fox News anchor compared the border situation in 2000 when "1.6 million people were stopped crossing the border illegally" to a year ago, when "less than a quarter that many were caught".

"I think we do", she said.

The authority being exercised by the White House is a relatively young, half-century old power delegated to the Executive branch by Congress, which is within its right to do. "Generally, it's a hard case to make that it constitutes the kind of a national emergency that would be able to support the president's move here", Panetta said. "Again, where's the emergency, the national emergency to build a wall?" In 2011, President Obama waged an entire war-the US-NATO bombing of Libya-without either authorization by Congress or an appropriation of funds. Is that not a fact? - it is undeniable that we have a major immigration problem and a political party that needs a permanent underclass of voters that wants that parade of illegal people who are uneducated, don't even speak the language. There have been 58 pronounced under the National Emergencies Act, of which 31 are still in effect.

"The Supreme Court has upheld the clear authority of the President to defend the national security of the United States", Trump responded in a statement.
