Republicans and Democrats aren’t budging in their fight over how much money to spend on President Trump’s border wall, which is increasing the chances of a stalemate that leads to a partial government shutdown next month.

President Trump has drawn a red line on the wall, telling GOP appropriators and leaders he wants $5 billion included in final fiscal year 2019 spending bill. The Homeland Security spending bill is where Republicans would like to include that money, and that bill needs to be passed by Dec. 7 to avert a partial government closure.
