The Georgia Republican seeks a sentence reduction, not a pardon, for Santos, who previously represented New York as a Republican in the U.S. House.

"I don't know if the Republican Party is leaving me, or if I'm kind of not relating to Republican Party as much anymore," Greene said.

In a letter Monday, U.S. Rep. Marjorie Taylor Greene formally came to the aid of the disgraced ex-congressman with a request that his seven-year prison sentence be commuted, arguing that the length of the term represented “a grave injustice.”
