Senate vote will be close with 3 republicans having already declared support for H.J.Res 46

"Sen. Thom Tillis (R-N.C.) on Monday night said he would join Republican Sens. Lisa Murkowski of Alaska and Susan Collins of Maine, along with 47 Senate Democrats to block Trump’s attempts to secure billions for his border wall after lawmakers effectively stiffed him. Now just one more GOP senator’s support for a resolution to block Trump's bid would send the measure to Trump’s desk and force a veto."

Trump is certain to veto. Congress would need a 2/3 supermajority to override the veto.
