A federal judge says a fired CIA agent can continue with a lawsuit challenging his dismissal from the agency.

The one-time covert agent -- identified only as Doe -- contends he was fired for refusing to alter intelligence the Bush administration wanted to cite in making its case for going to war with Iraq.

President Bush justified the war on grounds that Iraq had weapons of mass destruction. No such weapons have been found.

The judge ruled the former agent has the right to argue that his dismissal was based on allegedly false information placed in his file.

The plaintiff claims he was the target of two sham investigations launched by the CIA prior before his firing in September 2004.
