BOSTON (CBS) — The Massachusetts Congressional delegation is slamming President Donald Trump’s declaration of a national emergency to fund the construction of a wall on the U.S.-Mexico border.

Trump announced Friday that he’s declaring an emergency to free up billions of dollars in wall funding. Democrats are considering a lawsuit, arguing that the president’s actions are unconstitutional.

Here’s how members of Congress representing the Bay State reacted on Twitter:

Rep. Katherine Clark: The #NationalEmergency is a sham. The wall was never about security. It's a political applause line the President uses to stoke anti-immigrant sentiment. While his moral authority has always been in question, he is now violating Article 1 of the Constitution. #FakeTrumpEmergency

Trump said he is also anticipating a lawsuit but predicted he’ll prevail at the Supreme Court.
