Incoming White House communications director Anthony Scaramucci Anthony ScaramucciFormer DeVos chief of staff joins anti-Trump group Scaramucci to Lemon: Trump 'doubling down' on downplaying virus 'should scare' viewers Sunday shows - Leaked audio of Trump's sister reverberates MORE said 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.

"But unfortunately," he continued, "yesterday was my first day on the job. What you're asking me is on my agenda, if you invite me back next week, I'm sure I can talk about it with more depth and detail."

Scaramucci said the border wall was one of several campaign promises that Trump's team was eager to keep in order to prove they are different from "career politicians," who Scaramucci says get nothing done.

“We have a list of campaign promises that are up on Steve Bannon’s wall and we’re going right through those campaign promises and so that we can tell the American people that we are citizen politicians … we’re not career politicians or establishment players that just want to sit in Washington and milk the system,” he said Saturday.

The Trump administration has faced some criticism from those on the right over the progress of the wall, which was a top campaign promise for Trump.

Scaramucci was appointed White House communications director on Friday, despite reported pushback from Trump's current press secretary Sean Spicer.

Spicer resigned upon the appointment of Scaramucci and will leave his post on Aug. 15. Spicer's deputy, Sarah Huckabee Sanders, will replace him as press secretary.
