Incoming White House communications director Anthony Scaramuccisaid Saturday that the administration is “on missile lock” to build President Trump’s promised wall along the U.S.-Mexico border.

Speaking to Matthew Boyle on SiriusXM’s “Breitbart News Saturday,” Scaramucci deflected from giving further details, saying he hadn’t spoken to Homeland Security Secretary John Kelly, but that it was on a list of campaign promises that the administration is working on.

“I know the president has it in his budget, I know this is one of his campaign promises that he is on missile lock to keep,” Scaramucci said.
