Corn denied that Baker was a source for his story on the dossier.

“I’m not going to discuss my sources. But in order to prevent the dissemination of inaccurate information, I will say that James Baker was not my source for this story,” he said in a statement to POLITICO.

The congressional sources said there’s no conclusive evidence that Baker aided Corn’s reporting or acted as a source. But Republicans are pointing to the connection to cast suspicion about whether FBI officials had a hand in directing the details of the dossier to reporters, and the two sources said they expect it to be a focus of GOP investigators’ upcoming lines of inquiry.
