How have u. s. presidents contributed to traditions over time

They pardon a turkey every year.

Explanation:

There has been a presidential Turkey amnesty every year as like 1949 I believe. this is exactly where the leader justifies one turkey from growing cooked because covering 50 million turkeys are accepted up on Thanksgiving day .

the president was the speaker and it was a great part of history.

explanation:

video of the national aeronautic space administration's (nasa) coverage of president john f. kennedy’s address at rice university, houston, texas, concerning the nation's efforts in space exploration. in his speech the president discusses the necessity for the united states to become an international leader in space exploration and famously states, "we choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard."

i believe it is the bright red satin shirt.
