(AP Photo/Seth Wenig)NEW YORK The New York Mets will host the crosstown Yankees on the 20th anniversary of 9/11 next season, according to a person familiar with the decision. The clubs will play at Citi Field in a game sure to be full of emotions for the city that's also reported over 18,000 confirmed coronavirus deaths this year. I cant imagine how powerful and how emotional of an event that could be," Yankees manager Aaron Boone said. It'll be a homecoming of sorts for former Yankees manager Joe Girardi, who was hired as Phillies manager over the offseason.

ALEXANDRIA, Va. The only man ever convicted in a U.S. court for a role in the Sept. 11 attacks now says he is renouncing terrorism, al-Qaida and the Islamic State. In a handwritten court motion Moussaoui filed with the federal court in Alexandria last month, Moussaoui wrote, I denounce, repudiate Usama bin Laden as a useful idiot of the CIA/Saudi. At his final sentencing hearing, he told the judge God save Osama bin Laden you will never get him." Bin Laden was killed in a raid by U.S. forces on a compound in Pakistan in 2011. In particular, he says he wants either Rudy Giuliani or Alan Dershowitz to represent him as a lawyer, so he can testify in a civil trial filed by victims of the Sept. 11 attacks.

The Oklahoma City National Memorial and Museum has announced that it will offer a recorded, one-hour television program in place of a live ceremony to mark the 25th anniversary of the Oklahoma City bombing due to concerns about the spread of the coronavirus. But prosecutors would soon learn the Oklahoma City attackers were U.S. citizens and that their bombing was inspired by a different 1993 event. McVeigh had visited the compound during the 51-day standoff that preceded the raid, and prosecutors say that fueled his anger toward the federal government, culminating in the Oklahoma City attack. Acknowledging that the Oklahoma City bombing frequently is referred to as the worst act of domestic terrorism in U.S. history, McCann pointed to another atrocity in Oklahoma.
