SPOTTED: Bill Gates stepping off a crowded senators-only elevator with Sen. Rob Portman (R-Ohio) just outside the chamber on Thursday morning.

Portman’s office had no comment for The Hill about the Microsoft chairman’s visit to the Capitol.

It’s been a busy few days for the gazillionaire while in the nation’s capital.

After a full day of speaking at the The Atlantic’s Washington Ideas Forum, Gates was spotted having dinner at the modern Indian eatery Rasika West End in Georgetown on Wednesday night. We hear the computer whiz arrived with 10 guests.
