Emails obtained by The Detroit News say the goal was to either reverse the results, hold the total electoral vote count below 270, or simply call the results into question.
The emails were between two Trump attorneys and a campaign advisor. They regard presenting the false elector certificate to the National Archives and to Vice President Mike Pence, who presided over the official count.
The emails conflict with claims by state GOP leaders that the effort was to have Trump electoral votes on the record in case courts overturned the official results.
Fifteen Republicans who signed the certificate face state forgery charges. Charges against a 16th false elector were dropped after he agreed to cooperate with investigators.
