Green ribbons dotting the lapels of Democrats and Republicans attending President Barack Obama's State of the Union address were in honor of the 26 students and educators killed at a Connecticut elementary school in December.
Vice President Joe Biden's ribbon was most visible to TV viewers as he sat on the dais immediately behind Obama. Sharing the dais with Biden was GOP House Speaker John Boehner, who wore nothing pinned to either lapel.
Obama wore a small American flag pin, no green ribbon.
Obama put Biden in charge of developing gun control proposals in response to the Dec. 14 shooting at Sandy Hook Elementary School. The proposals before Congress include a ban on assault weapons and ammunition magazines holding more than 10 rounds, and background checks for all firearms purchases.
