UPDATE (8:43 p.m. EST):
NBC has replaced this woman's comment about Muslims with a less inflammatory comment: "I'm scared to death for my country. I believe Obama is running this country into the ground."
This appears to be the only edit made to this online video. Footage of her previous comment does not appear to be posted. The original video was broadcast Saturday evening, Sept. 12, 2009, on NBC Nightly News.
A protester at Saturday's Tea Party on the National Mall in Washington, D.C. made clear that she was afraid, saying "We are losing our country, we think the Muslims are moving in and taking over."
NBC Nightly News interviewed the woman, who was surrounded by fellow protesters as she made the remarks. Her name was not used.
Participants at the event, billed "March on Washington" by its organizers, rallied against President Obama's health care plan and what they say is out-of-control spending.
