Several bipartisan congressional negotiators have reached a deal, in principle, to fund the government and avoid another government shutdown at the end of the week.
No one involved has given any details on the agreement, including whether U.S. President Donald Trump will get all the money he wants for a wall along the U.S. southern border.
Democrats have offered some funding for border security -- far less than what Trump has said he wants he wants for a wall.
The president is in El Paso, Texas for a rally Monday night to focus on the wall he says would thwart people from illegally entering the United States from Mexico.
El Paso's former congressman, Beto O'Rourke, who is considering a possible run for the Democratic nomination in the 2020 presidential race, is leading a march in opposition to Trump's wall demand.
Acting White House Chief of Staff Mick Mulvaney has told NBC News another shutdown "absolutely cannot" be ruled out.
Trump has not publicly stated what level of funding he would accept as a compromise to build a barrier along a relatively small portion of the 3,200-kilometer U.S.-Mexican border.
