Congressional critics do not appear to have the votes to override Trump's veto. So, as a practical matter, the administration can continue to spend billions of dollars more on border barriers than lawmakers authorized, unless and until the courts intervene.
"Today I am vetoing this resolution," Trump said, flanked by law enforcement officials at an Oval Office event. "Congress has the freedom to pass this resolution and I have the duty to veto it."
Also in the room for the veto signing Friday were parents of children who were killed by immigrants who entered the country illegally, as well as Vice President Mike Pence, DHS Secretary Kirstjen Nielsen and Attorney General William Barr.
"I don't know that I've ever been more proud than to be standing next to you today," Pence said. "You're keeping your word by vetoing this legislation."
