Trump doesn't pay for anything, including his own bills.   He is, unbelievably, trying to get the republican national committee to pay for the attorneys he has hired to manage the whole russia mess.

In the meantime, even if funding is approved for a wall, it is likely to go nowhere real fast.   Any construction will be held up for years with the more than 90 lawsuits filed opposing federal seizure of private land needed for the wall.   Looks like trump followers will be waiting a long time for any "accomplishments" by their moronic leader.
