I read this in an article from Market Watch: "Democratic presidential candidate Bernie Sanders will take time off the campaign trail ahead of the critical New York primary for a trip to the Vatican next week, his campaign said Friday.
The Vermont senator will participate in a conference on social, economic and environmental issues April 15, alongside Bolivian President Evo Morales, Ecuadorean President Rafael Correa and others, his campaign and the Vatican said."
And this statement was in ABC news: "The trip was organized and paid for by Sanders’ campaign."
Isn't there a clear violation of the use of campaign funds here? I know there is probably a sort of gray area as to whether the conference is considered campaigning, but doesn't his campaign stating that it was "time off the campaign trail" point to a violation?
