Legal fights brewing against Trump\'s declaration

(SOUNDBITE) (English) U.S. PRESIDENT DONALD TRUMP, SAYING: "Look, I expect to be sued.

I shouldn't be sued." The legal challenges to President Donald Trump's national emergency declaration are coming, with one suit already filed and at least two more expected.

A group in Texas filed the first lawsuit on Friday, saying Trump's declaration violates the U.S. Constitution AND that the planned wall would infringe on their property rights.

(SOUNDBITE) (English) U.S. PRESIDENT DONALD TRUMP, SAYING: "We're gonna get it done." Trump made the emergency declaration Friday.

The White House said it allows him to redirect roughly $8 billion to fund his U.S.-Mexico border wall without congressional approval.

Under the U.S. Constitution, Congress has authority over federal appropriations, not the president.

New York attorney general Letitia James said she would use "every legal tool" at her disposal to fight Trump's action... while California Governor Gavin Newsom vowed action as well.

GAVIN NEWSOM, (D) - CALIFORNIA, SAYING: "Fortunately Donald Trump is not the last word, the courts will be the last word." The Democratic-led House Judiciary Committee also launched an investigation into the declaration.

Legal experts say the challenges face an uphill and probably losing battle, likely to go before the conserative-majority Supreme Court... similar to Trump's travel ban which was upheld by the court last year after the justices gave the president the final call on immigration and national security issues.

The challenges are also likely to delay the use of the funds and could drag the legal fight into next year's election.

Trump has painted illegal immigration and drug trafficking across the border as a national security threat.

Even though statistics show that illegal immigration at the border is at a 20-year low AND that many drugs come through legal ports of entry.

When confronted with those stats on Friday, Trump said they were wrong.
