Police say Democrat Cynthia McKinney hit a policeman on 29 March after he stopped her at a security check in a government building.
The row has escalated, with Ms McKinney arguing that the issue is one of racial profiling at Congress’ security checks.
However, few lawmakers have backed Ms McKinney and counter accusations have been directed at her.
House Speaker Dennis Hastert said the security checks were about safety, not racial profiling.
And former Republican majority leader Tom DeLay went further, accusing Ms McKinney herself of racism. “Everything is racism with her,” he said.
