https://www.bbc.com/news/world-us-canada-46657393 Trump got the message from his base this week, via Fox News et al, that the wall is a "do or die" issue. If it doesn't happen now before the Dems take over the House, it aint happening. The House passed a spending bill that included border wall funding, but Senate Dems refuse to pass it. So as if midnight last night, the US government is partially offline. Dems may end up budging because they're enthralled to union workers that suffer. But a long shutdown means the stock market will continue to tumble, which is bad for Trump. Perhaps Senate Republicans should go nuke and reduce the vote requirement to 51.
