BUMP Act
Key: what the circles and colors mean
Each circle is a bill. The ring fills as it moves through Congress:
Under the number: the Yea · Nay count of its final (or latest) recorded vote. On a member's page, the small badge is how that member voted: Y Yea / Aye, N Nay / No, P Present, – Not voting.
Gold and violet are only for Yea and Nay; they never mean a party. A member's party is the letter on their photo.
Not yet voted on. This bill is still a proposal: it hasn't reached a floor vote, and its text can change in committee or on the floor before any vote.
