The Republican majority wants to cut taxes and pass a costly infrastructure bill, but Trump has threatened to trigger a government shutdown unless it funds his wall.
"But he's not saying that Mexico is going to pay for it now", a reporter said.
President Donald Trump on Sunday renewed his push to build a wall along the southwestern border, promising yet again that Mexico will end up covering the construction costs. In a press conference, perhaps with a freshly pardoned Sheriff Joe Arpaio by his side, he will announce that the wall is finally being built, "big lovely door" and all. "We have an all out effort going, and going well!"
It said the crime is a "shared problem" for both countries and is caused in part by US' demand for Mexican narcotics.
The US government says it's now looking at more building proposals, but not everyone agrees that a wall will be enough to bring the smuggling of drugs and people to an end.
White House Homeland Security Adviser Thomas Bossert defended the approach Sunday on ABC News' "This Week".
"What we'll do here is go through the mechanism of getting the original initial money that we need for that capital project from Congress through an appropriations process and we'll responsibly construct the barrier on the border", he said.
The Foreign Ministry said in its statement that Mexico will not negotiate NAFTA or any other aspect of the bilateral relationship "through social networks or the media". At the same time, according to the report, he said, "If you are going to say that Mexico is not going to pay for the wall, then I do not want to meet with you guys anymore because I can not live with that".
Trump also asked his 36.8 million followers on Twitter if he should continue negotiating the North American Free Trade Agreement (NAFTA) with Mexico and Canada.
The U.S., Mexico and Canada began formal negotiations earlier this month to rework the 23-year-old trade pact that Trump blames for hundreds of thousands of lost U.S. factory jobs.
'We are in the NAFTA (worst trade deal ever made) renegotiation process with Mexico & Canada.Both being very hard, may have to terminate?' Trump tweeted Sunday morning.
