The past week marked a somber milestone in the United States as we stopped to remember those killed in the September 11 terrorist attacks 20 years ago.
Memorial services were held in New York, Pennsylvania and Virginia, and President Joe Biden visited all three sites. In New York, he was joined by former Presidents Bill Clinton and Barack Obama.
"These memorials are really important," Biden said during his stop in Pennsylvania. "But they're also incredibly difficult for the people affected by them, because it brings back the moment they got the phone call, it brings back the instant they got the news, no matter how years go by."
