A veterans group is threatening to sue because they are not being allowed to march in the Veteran's Day parade.
The group is called Veterans for Peace. Many of the members were wounded in battle and they are now anti-war.
In past years, the group marched in the parade, carrying a flag covered casket. They say they did that to honor their fallen friends and show their opposition to violence and war.
They wanted to read an anti-war statement in this year's parade, but organizers didn't want them to do that and denied their application to take part.
Now Veterans for Peace is threatening to sue to be allowed in.
"They don't want us in the parade not because we carry caskets... they don't want us in the parade because we refuse to abide by their view of patriotism, which is war is good, peace is bad," said Richard Smith.
The group protested outside Phoenix City Hall on Wednesday, but the city says they are not sponsoring the event and have no say over who gets to participate.
