Washington (CNN) The Virginia House Republican leader said anyone spreading "white supremacist garbage" is not welcome in Richmond after a state of emergency was declared because of threats surrounding a gun rights rally planned for Monday.

"Any group that comes to Richmond to spread white supremacist garbage, or any other form of hate, violence, or civil unrest isn't welcome here," Todd Gilbert said Saturday in a statement.

Federal authorities arrested a number of suspected neo-Nazis around the country this week out of concern that they were planning violent acts at Monday's gun rights rally in Richmond, a senior FBI official said Friday. Seven men accused of belonging to a white supremacist group called The Base were arrested this week in separate raids in Delaware, Georgia, Maryland and Wisconsin, according to authorities.

"House Republicans reject any attempt by any group to infuse any kind of twisted or extreme worldview into this fundamentally democratic exercise," Gilbert's statement continued. "So there's no mistake, this is my message to any group that would subvert this event: you are not welcome here."

"While we and our Democratic colleagues may have differences, we are all Virginians and we will stand united in opposition to any threats of violence or civil unrest from any quarter," Gilbert said. Gilbert represents the 15th district in the Virginia House of Delegates.
