President Donald Trump's "first buddy," Elon Musk, was seemingly everywhere in D.C. on Inauguration Day. Where (and with whom) was the billionaire?

Elon Musk has been spotted at the White House West Wing, sources say. Musk is said to have a blue badge -- which is essentially an all-access pass. Musk has office space in the Eisenhower Executive Office Building -- or the EEOB -- which is in the White House complex but situated next door.

Feeling vindicated by voters despite his impeachments, indictments and conviction on 34 felony counts, Mr. Trump intends to move quickly beyond Inauguration Day rituals to put his stamp back on the government.
