A group of sixteen states sued the Trump White House Monday (February 18) for declaring a national emergency to get funds for a border wall.
The coalition is led by California.
Their lawsuit follows Trump invoking emergency powers last Friday (February 15).
The U.S. Congress had declined his request for $5.7 billion to help build the wall.
California's attorney general said in a statement, quote, "We're suing President Trump to stop him from unilaterally robbing taxpayer funds" and that "the Office of the Presidency is not a place for theatre." News of the lawsuit came as hundreds across the U.S marched against the president on a national holiday.
(SOUNDBITE) (English) PROTESTER IN PHILADELPHIA, SAYING: "It's ironic that we are here on President's Day not to honor past presidents but to unite in a fight against the current president and his power grab by declaring his national emergency." The coalition says they could use the President's own words on Friday against him: (SOUNDBITE) (English) PRESIDENT DONALD TRUMP SAYING ABOUT FUNDING FOR HIS BORDER WALL: "I could do the wall over a longer period of time.
I didn't need to do this.
But I'd rather do it much faster.
Trump's earlier comments - saying he knew he didn't need to declare invoke emergency powers - could now undercut the White House's legal argument for the move.
It may also be used as evidence that there is no national emergency to declare.
It's not Trump's only legal challenge on the wall.
Three landowners in Texas and an environmental group filed the first lawsuit on Friday.
They say Trump's move is a violation of the constitution and would infringe on property rights.
The wall is a signature campaign promise for President Trump.
