Building a wall on the US-Mexico border was one of Trump's key promises throughout his presidential campaign. The president believes that the wall will stop illegal migration, as well as human and drugs trafficking.
Commenting on the situation, the US president wrote on Twitter that "one way or the other" he will win on the wall.
Congress has until Friday at midnight to pass funding bills for several government agencies, including DHS, in order to avoid a partial shutdown of the federal government.
President Trump has also repeatedly insisted that Mexico have to pay for wall. In a tweet published on Wednesday he said "Mexico is paying 9indirectly0 for the Wall through the new USMCA, the replacement for Nafta!"
US President Donald Trump, then-Mexican leader Enrique Pena Nieto and Canadian Prime Minister Justin Trudeau signed on Friday the United States–Mexico–Canada Agreement (USMCA).
The USMCA, set to replace the North American Free Trade Agreement (NAFTA), has to be ratified by the three countries' parliaments.
