 -- In an unexpected sighting Tuesday, former Vice President Dan Quayle showed up at Trump Tower to offer his "personal congratulations" to President-elect Donald Trump, who has been meeting with potential Cabinet picks this afternoon.

"I was in the area and I stopped by to see the president-elect to offer personal congratulations to him. I talked to him recently on the phone," Quayle told reporters following his meeting. "Things are in good hands. He's moving forward and he's going to make America great again."

Quayle also confirmed he had breakfast with Vice President-elect Mike Pence this morning.

The former vice president to George H.W. Bush announced in May he was backing Trump and expressed his confidence that the real estate mogul could beat Hillary Clinton.

"I'm going to support the nominee," he said in an interview at the time on the "Today Show." "And I predict that most people in my position or people that have been in the Republican Party for a long time will rally around the nominee."

During the interview, Quayle said Hillary Clinton was more qualified to be president "on paper," but argued that Trump is "more qualified in the sense that the American people, I think, want an outsider."
