Johnson has since said that he knew nothing of a fake elector scheme, which is now part of a sprawling federal investigation.
The Wisconsin lawsuit alleges that Troupis was a link between the Trump campaign and the fake electors, and allegedly relayed the strategy behind the scheme to Trump allies in Wisconsin.
“He’s changed his story a couple of times on handing off fake electors to the vice president or trying to,” Franken said in an interview with NBC News.
After Pence’s staff told Johnson’s aide not to give them the slate of electors Jan. 6, Johnson said he informed Troupis.
At a recent event at the Milwaukee Rotary Club, Johnson was asked about his actions around Jan. 6.
