As the nation pauses to remember the 9/11 terrorist attacks, many ceremonies are still planned, but with modifications because of the pandemic.
President Trump and Democratic challenger Joe Biden are both headed (at different times) to pay their respects at the Flight 93 National Memorial in Pennsylvania.
Vice President Mike Pence will visit a socially distanced ceremony at ground zero in New York City.
The Pentagon's observance is so restricted that not even victims' families can attend.
Nearly 3,000 people were killed when hijacked-planes attacked NYC, the Pentagon, and Shanksville, Pennsylvania.
