Critical constitutional concerns emerge as the president subverts Congress to create his own tax and spending policies

The Trump administration said Tuesday it will use tariff funds to keep afloat a federal food assistance program for nearly 7 million pregnant women, new moms and young children during the government shutdown.

White House press secretary Karoline Leavitt says the Trump administration has to look at ways to "save money in a responsible way that respects the American taxpayer's money" during shutdown.

In the battle of public opinion, the White House and the GOP appeared to be taking more of the blame for the shutdown than Democrats. In a new CBS News poll, 39% said they mostly blame Trump and Republicans, while 30% blame Democrats in Congress and 31% blame both equally.

White House press secretary Karoline Leavitt is scheduled to address reporters Monday afternoon as the government shutdown enters its sixth day. President Trump has stayed out of the fray on Capitol Hill,

The partial government shutdown stems from congressional disagreement over healthcare provisions, whereas the previous shutdown pitted the White House against lawmakers.

White House economic advisor Kevin Hassett told CNBC on Monday morning that the government shutdown will cost the U.S. GDP about $15 billion per week.
