Several organisations brought lawsuits over the declaration, and House Speaker Nancy Pelosi said on Thursday that Democrats also planned on suing to prevent Trump from "stealing" money from federal programs and diverting the money to build a wall.
That's an apparent mirage as Trump retreats from his latest threat to seal off the USA from Mexico. The California Democrat says money transfers to the wall have "undermined our democracy" and flout "the vote of the bipartisan Congress, the will of the American people and the letter of the Constitution".
But Trump, who ratcheted up his hard-line immigration rhetoric in recent weeks, declared that his move, which included vetoing a congressional vote, was necessary.
Many families straddle the border and cross frequently in both directions to visit loved ones.
Trump defied decades of precedent as a presidential candidate by refusing to release the tax documents and has continued to keep them under wraps as president, saying his returns were "under audit" by the IRS.
Trump argued that many migrants crossing the border illegally are making bogus asylum claims.

Coveney added that Ireland plans to support Britain's request for a short further delay to its European Union exit. The offer of the olive branch was accepted by the Labour leader, who said that "we will meet the prime minister".
"I am looking at an economic penalty for the 500 Billion Dollars in illegal DRUGS that are shipped and smuggled through Mexico and across our Southern Border".
Trump, on why he is pulling back on sealing the border imminently: "Because Mexico has been absolutely terrific for the last four days".
Before leaving for California on Friday, Trump said he still "may shut it down at some point", but that he was focused instead on issuing tariffs against automobiles from Mexico as a potential punitive measure.
Trump indicated that closing the border is no longer on the cards at present, but reiterated a new warning that he will impose 25 percent tariffs on auto imports from Mexico if illegal migration and drug smuggling is not controlled. "We may have to go a very tough way", Trump said in an interview with "Fox & Friends Weekend" that aired Saturday. He emphasized that it was fuelled by US demand. After this Trump told people who were performing in Mexico City on the crossroads in Mexico City, that the USA is filled, we cannot keep more people here.
"The asylum program is a scam", Trump said. Arrests along the southern border have soared in recent months, and border agents were on track to make 100,000 arrests or denials of entry in March, a 12-year high.
For example, many so-called "Unaccompanied Alien Children" are being smuggled up the border because Trump's agencies will pass them to their illegal immigrant parents living throughout the United States, under policies set by Obama. The White House did not respond to a request for elaboration. "Our relationship with the government of the United States is very good", he said. Referring to the recently concluded investigation by Special Counsel Robert Mueller, the president added: "I know about hoaxes".
