The U.S. economy is taking a larger-than-expected hit from the partial government shutdown, White House estimates showed on Tuesday, as contractors and even the Coast Guard go without pay and talks to end the impasse seemed stalled.

The shutdown dragged into its 25th day on Tuesday with neither Trump nor Democratic congressional leaders showing signs of bending on the topic that triggered it — funding for the wall Trump promised to build along the border with Mexico.

Trump invited a bipartisan group of members of Congress for lunch to discuss the standoff but the White House said Democrats turned down the invitation. Nine House Republicans — none of whom are involved in party leadership — attended the private lunch.
