Trump didn't call for a government shutdown. If you quoted Trump in context, it is the Democrats who want a shutdown, because they know the [liberal] media will blame Republicans no matter what. Trump basically said that if it takes a shutdown to clean up government, then bring it on.

But Sen. McConnell took the possibility of a shutdown off the table from the outset, so the point is really moot. Whatever Trump's bravado remarks, it will never happen because of the establishment Republicans.
I personally don't want a shutdown, but I still want it to be a viable possibility, for negotiation purposes with the spiteful obstructionist Democrats. Taking it off the table as even possible just hands a win to the corrupt Dems.
