Nancy Reagan falls at political event

NBCBayArea.com reports:

Nancy Reagan tripped and fell Tuesday night during an event at the Ronald Reagan Library in Simi Valley.

As the former First Lady was escorted to her seat, she appeared to have lost her balance and fell down. The crowd gasped, but Marco Rubio (R.-Fla) and others helped her get to her seat.

Reagan Library spokeswoman Melissa Giller told NBC4 Mrs. Reagan remained at the event and was not injured. Giller said the room was packed and Mrs. Reagan apparently tripped on a post used for crowd control.

The widow of the 40th president of the United States is 90 years old.
