Obama voted on all amendments and the cloture vote, but missed voting on the final bill which took place yesterday at 5:30 PM, he was probably traveling to Wisconsin at that time.
Clinton was not present for any of the votes and voting started yesterday just after 10:00 AM. It was reported that she was in the area of DC earlier in the day before traveling to Texas.
Final passage vote link (vote # 20) shows a time of 7:30 AM ??? although the vote on final passage did not occur until 5:30 PM.
